Garmin e-Trex GPS -> XDA

Hi,
Just wondering if anyone has successfully hooked up a Garmin E-Trex to an XDA. It should be possible using the serial connector from both (null-modem!?!). If so what software was being used on the XDA.
Cheers
Jeff

Garmin eTrex - XDA
The eTrex and XDA make a great combination even with Pocket Streets: the eTrex gives you the vector to your destination and the XDA shows you where you are on the map at zilch cost. The draw back is that you can find your target destination on PStreets but there doesn't seem to be a way of extracting the coordinates to feed into your eTrex.
So I got the TomTom Citymap of London to try that out and after a poor user experience when the supplied gps driver locked the XDA up and I had to download another, plus no explanations of various 2.06 driver features plus finding that parts of the M25 London orbital were chopped off, I have the best of both worlds. It only cost me 10UKP.
Oh yes, connections. You can buy a TomTom power/gps cable for the XDA that is meant to take the TomTom gps mouse via a 4 connector phone type socket. So all you have to do is come up with a 4 connector phone type plug leading off to you eTrex. If you have the eTrex car cable for power and RS232, which you might want to use with a laptop, you will not want to cut this. So get a cheap RS232 cable and chop the appropriate end off for your phone type connection. Marry everything up, ignore the wife's complaints about wires and delayed departures while you fiddle with the eTrex and XDA, and you are off.
The TomTom cable phone socket housing can be taken apart briefly to check which are the Common, TX and Rx wires, and the tiny circuit board even tells you which is which. If you want I can give you the pin outs but at the risk of misinterpretation.

Etrex GPS
Managed to get it to work with Navigator and am well impressed.
Got a cable from http://pc-mobile.net/gps.htm. However had a few problems to start off with. The XDA ground to a halt (I have updated the ROM to the latest O2 release and apprently TomTom 1.4 has a problem with later version). Updated TomTom to 1.51 and still no joy. Change the interface from Garmin to IMEA 4800 baud on both GPS and TomTom and had a great weekend driving up and down the motorway and country roads in Derbyshire.

Jeff,
Cool, isn't it! Perhaps you can enlighten me about Navigator. Not knowing much about TomTom I rather expected voice prompts on the citymap thingy I downloaded. Question: what do you have to do to get the voice prompts invoked (spend more money probably) and can you hear them from the XDA? :?:
Ken

Navigator Talking
I have Navigator 1.51 installed (downloaded from Tom Tom site) only you need at least a previous version as otherwise there are no maps.
When you do a route plan (rather than just have it in map mode), it does the "300 yards turn right......turn right.....find the next convenient place and turn round"
Not sure what happens with previous versions as I had 1.4ish on before and that interfered with Windows as I had upgraded PPC2002 to a newer version and it odesn't like that too well.
Cheers
Jeff

Hi guys, do you know if the connector for the Garmin Geko 201 is the same as the Etrex? I was looking at buying the Geko and the cable from the site listed above but they don't say specifically for the Geko. I put an email question in to the cable guys but you never know how long it will take to get an answer. It's definitely a flat connector and not a round pin type. Thanks - Jim

Hi,
I've bought a Fortuna U2 GPS receiver with an O2 XDA lead.
I've downloaded some software (GPSeasyCE), but when I try and connect to the GPS unit, I get "unable to open COM1".
Any suggestoins please?
I have tuned my keyboard driver to IR & serial, and I think I'm using the correct com port settings (4800bps, NMEA 0183).
I'd really like to just check that the hardware is working.
Can I download some free demo software that will do that?
What's best?
Thanks in advance, for any help anyone can offer,
Muddy

You have to turn off the IR port.

disable your infra red port under setting, connections/beam, it will then work. A point about cables to work with gps, if you get a serial xda cable, and you also have a pc serial cable that links to your gps, all you need to do is get a 9 pin male to 9 pin male null modem adaptor, or make one, you need to join pin 2 on one to pin 3 on the other, pin 3 to pin 2 and pin 5 to pin 5, plug your xda lead one end, gps lead the other, and away you go.

GPS Receiver won't work :( Please help!

I have just got a Rikaline 6010 GPS unit, and make a cable that go's from the Ps/2 Connector to the XDA connector.. the GPS powers on, but Tomtom doesn't appear to be getting any data, on the GPS screen the little Satellite - - - PDA area is not showing any data being sent/received.
The PDA works fine, as I have it hooked up to my Digitraveler (Rikaline is for my dad)
I have tried selecting TomTom GPS Receiver, Rikaline 6010, NMEA 4800 from the GPS menu but none of them work
Rikaline have the Pinout in their manual: http://www.rikaline.com/download/GPS-6010-Manual-E.pdf
I have the RS232 TX & RX connected to Pin 8 & 10 on the XDA connector.
GND is on Pin 5 of the XDA connector, and +5 is taken from cigarette lighter.
Is this correct ?
Should I be using the TTL connections instead ? where would they go on the XDA ?
Many Thanks
Neil

Have you tried reversing the tx/rx connections, worth a try? How are you powering the gps?

GPS is being powered from ciggy lighter in the car, I've just made a PC cable and tried using some diagnostic software to read the raw data from the GPS and nothing
I think the unit may be knackered...

Well..... what do ya know! I thought what the hell.. i'll swap the data leads round and see if it makes any difference even though both cables were wired EXACTLY as is shown in the GPS manual. But IT WORKS!!
The unit can seem to hold a lock though, I will get one in about 20 secs if I unplug it and then plug back in, but after a minute or so it drops and never gets a lock again.
Could it be that the ciggy lighter (one supposed to be used to charge XDA) is not powerfull enough to do the XDA and GPS (the GPS doesn't appear to actually turn off when its losing the lock)
Cheers
Neil

Is it possible for you just to feed the gps with power using that adaptor? You could switch off power management on the xda temporarily so it stays on while experimenting.

Ok it doesn't appear to be a power thing, as the GPS does exactly the same thing when using my laptop, it will get a lock and hold the lock for exactly 2 minutes then the unit appears to power cycle as it loses all signal.

Certainly sounds like a component failure, can you return it or is it cannibalised?

Sent it back this afternoon, the unit has not been touched. Just made the XDA > Male PS/2 Connector, so hopefully it will work when the new one comes

ive also got the same uit and struggling to get it working i have tried to swapp the pins around too but nothing gps powers up and works fine but its not senidng data to the xda
looking at the datasheet i have connected the Rx RS-232 and Tx RS-232 to the pins 8 and 10 are they the right RX/TX's? as there are Rx TTL and Tx TTL too?
lmk cheers :\
----edit------------
works ok with only one cobination but it shows the dots going to the pda on the gps screen but it stops after about 4-6 little dots then doesnt do nothing
HEEELLLP!!!! lol dont tell me i brought yet another bluddy gps and it dont want to work with my xda

A few Nook HD questions

Hi, I'm thinking of getting a 7" tablet to install in my car, I'm not looking for anything super high spec as I'm literally just going to use it for mapping and playing music. That being said, the nook HD looks like a really good spec for the price..
I've just got a few questions
It doesn't have GPS, but I assume it will work using a bluetooth GPS once I've installed CM10?
I understand it uses a proprietary usb cable, how far does it stick out? Does anyone have a picture of it? This may be me only problem mounting it in dash as I wont be able to find a right angled one!

Yes, you can use a Bluetooth GPS puck. I haven't gotten Google Maps to work with it yet but I have gotten other programs to see it. A 3rd party GPS program should work with it. I'm still planning on testing that theory but to much family stuff has been going on right now to actually do it.
With the connector and the way the cable is wrapped right next to it it sticks out about an inch (just a little under that) from the bottom of the device. I'm pretty sure that to much pressure on that part of the cable will make is useless so you would have to make allowances for it. Also, it needs more power than a normal micro usb cable to actually make it charge. The AC adapter puts out 1 volt at 2 amps.

Got Sygic working today. Had to use this program to get it working though. https://play.google.com/store/apps/...?t=W251bGwsMSwyLDYsImRlLm1vYmlsZWouYnRncHMiXQ..
Other then that seems to work quite well. I should mention that I am on CM10.1.

I got Google maps to work fine with my phone using Bluetooth for gps and Wi-Fi for data.
Have to see up maps to accept debug data and use bluetooth gps programs on both devices

Nexus 7 Car Install

I've decided to put together a Nexus 7 car install after pricing up an OEM retrofit for my E90 & quickly getting north of £1200 with no guarantees that everything would work as I wanted.
I've used Android devices to provide navigation & audio since getting a HTC Desire many years ago, but I've been caught out a couple of times recently using navigation on long journeys with my HTC One-X completely flattening its battery despite being on charge the whole time!! The last time left me navigation-less in a strange city, in rush hour traffic, with no way to contact anyone.
I've been reading around Nexus 7 car installs today & everything that I would like to do seems to have been done before, but I'd like some ideas for the best way to pull it all togther.
The main use for the Nexus will be to provide navigation & audio. I gather that Timur's kernel - USB ROM contains features which are suited to using the Nexus in a car install - are there any other ROMs I should have a look at?
I would like the install to look as professional as possible but be removable & reversible, so I'm thinking of a mounting it in a SHG-NX2000, & I would prefer to use a single USB connection to the Nexus rather than a USB & 3.5mm so from my googling today I gather I can achieve this with an OTG USB cable & a USB DAC.
I've not used an OTG cable before, but the ones I've seen on ebay seem only to be a couple of inches long - can anyone provide a link to longer one or can I just use an extension cable & stick the OTG cable near the hub? The idea I've got in mind is to run the host OTG cable from the Nexus into a powered USB hub located in the glove box or behind the dash. I would supply the power to the hub from a DC-DC convertor to make sure everything gets the power it needs. Are hubs usually wired to supply power to the host device as well as the connected devices? Are OTG cables available which allow the power to be supplied to the host? If so, I could use one of the ports on the powered hub to supply power to the Nexus via the OTG cable.
I don't have a spare line level input to my stock BMW headunit, but I do have an aux in on a 3.5mm socket which I don't mind re-routing & hard wiring to the output of the DAC - can someone link to a USB DAC best suited to this task?
I would also like to install a reversing camera. There are cameras available which either replace a license plate light, or mount around the license plate - I would prefer to use one of these over a webcam. I had an idea of using an Easycap to connect the license plate cam to the USB hub - has anyone done this? The license plate cams pick up their power from the reversing lights - is there a way of using the fact of the camera powering up to switch the Nexus to auto display the feed from camera when the car is put in to reverse? Taking this idea a step further, has anyone configured a system where if the car is then subsequently taken out of reverse gear the Nexus switches to a forward facing camera either for a fixed amount of time or until reverse gear is re-selected to give you alternating rear/forward views when parking up?
Shopping list so far:
Nexus 7 (1st gen) £119
SHG-NZ2000 £22.39
DC-DC convertor £5.50
10-port powered hub £6.19
Micro USB OTG Host £1.99
E90 License plate light CCD camera £17.00
Easycap £3.37
USB DAC £11.49
Total so far ~£185
Anything I've missed? Better components? Cheaper prices?
Any help or ideas greatly appreciated

I would think the only way for a rear cam to work is to modify it and your tablet ...no usb input... You could try to use the housing of a rear cam and put a web cam it and seal it up good then use that .... That way you'll get a wide veiwing angle ....

I'm not sure I understand what you mean by 'no usb input'? I'm talking about connecting the CCD camera via the Easycap to the USB hub which is connected to the Nexus. It is because I don't think I'll be able to reseal the housing well enough that I don't want to use a webcam, plus the CCD cameras are powered when reverse is selected which I'm hoping should make driving an event easier.

Found this on a BMW forum:
Finally sewed up my Nexus 7 install!
It's very similar to what I had in mind. I've ordered the bits so I'll update this thread as & when progress is made.

i was thinking of use official dock mound to the dash to make it look professional and removable(dock + magnets).
not sure if the usb on the back of the dock supports otg or not, cos i wanna connect up reverse camera and dac aswell

I considered doing something similar, but when I looked into it, it would seem that the official dock only charges and passes audio

Hi there,
I was just wondering if you had any success with the camera? I've got a Nexus 7 install and want to wire in my existing Rca cam. I'm sorting out the reverse signal with a joycon exr steering wheel control but I want to know if the easycap thing you linked to earlier worked as a capture device on Android or whether I'd have to go for the UVC grabber in the other link which definitely works but is much more expensive!
Thanks!

Any update on these types of cameras?
I want to do the same thing, except the camera is in the front (not the back).
Any success with the EasyCap? It seems they have bad reviews on amazon, but maybe they work great for how we want to use it.
Also, have you tried using a 4 channel EasyCap? That way we could hook multiple cameras.

nexus 7 install
In the process of doing the same to mine.
2013 Nexus 7 rooted with automateit and tasker .
So far I've managed to get it to launch apps when power is supplied and shutdown when power is disconnected. But does anyone know of a way to get it to power on when power is supplied? I've tried reboot when power is supplied, but that only works if the tablet is already on.

Which OBD2 adapter?

I have old OBD2 v1.5 adapter. Chinese, big one. Which pairs with HU and works well.
I wish to buy new one, that call 'mini'. I know I have to look for v1.5 (as 2.1 is a crap) and with PIC18F25K80 chip.
But I read that even much of these new mini are PIC based, that have some strange Mac address like AA:BB:CC:11:22:33.
Anyone has experience with such adapters? Do they pair and work with Torque on our HUs?
If anyone is using such an 'mini' adapter, please post link to eBay/AliExpress where you purchased it. Will be very grateful (and it may help other people here, too, as many have issues pairing/using crap adapters).

I personally bought https://www.ebay.com/itm/Auto-16-Pi...le-Diagnostic-Adapter-For-elm327/152700822059 and https://www.ebay.com/itm/2017-ELM32...uto-Car-Scanner-Scan-Tool-Cable-/112070132071 so I connected it over USB and only thing I've made is HW MOD to get ACC+ instead BAT+ from OBD2 so that it is powered only when Key is turned on.
Resolved pairing issue with no pairing and all works along with BT and WiFi free for other devices.

Thank you for sharing. I was not considering USB option, but it sounds interesting.
I see you both the 'big' one (same as my old one). And they really work very good.
But I would like to buy some of 'mini' models as my OBD2 port is in such place (under steering wheel and just above brake pedal) that big one is too big and my feet is hitting it while driving. Here is obe model I consider

There are 2 models of these (not colours): old design with 2 PCB boards, and new one with just 1 board. I wonder if anyone has any of these?

:silly: I do not see the problem there as if you checked both links from my post you would see that I use extension cable that do not have issue with connector position. Mine is located right above gas pedal so I could not drive car normally with any OBD Adapter unless I used extension cable.

PIC is programmed micro controller and not actual ELM327 see https://www.elmelectronics.com/products/ics/obd/ and v1.5 nor v2.1 exist officially as they are clones and you should use https://play.google.com/store/apps/details?id=com.applagapp.elm327identifier to test actual model and support.
Re which one: I ordered 6 different models and kept two that worked flawlessly with my car 1 was broken (got refund) and resold other 3 to get my money back.

It is fairly simple MOD:
1. Soldered positive wire of lighter connector that have power only when Ignition is turned on.
2. Bought FLAT cable that I can easily cut the wires like in picture s-l1600.jpg
3. Cut Wire on pin 16 BAT power see ODBII%20Master%20Pinout.jpg
4. Connected wire that goes to OBDII to Positive wire I prepared in step 1
5. Connected OBDII to connector from FLAT CABLE
6. Connected USB to HU SINGLE USB CABLE
7. Tested if all works with Toque
8. Used cable ties to secure all cabling behind dashboard
and now I enjoy the all the diags on HU

Thanks for this info, very helpful, just got Android 8 Eonon 2170, and I've been struggling to pair OBD, Kiwi 3 doesn't show (BLE not supported? Don't know), Tomtom unit won't pair, no name unit seems to work, but, I've thought, why not USB, started searching for USB Android supported, luckily came across your post.
To change BATT to ACC, is that just so it's ' done properly'?
Surely battery drain would be miniscule, or not? I guess makes sense to have it not powered all the time.
Going by your posts, so, some of these units didn't work properly,ECU side or Android side? Thanks again, A

I just looked into factory settings, there is a CANBUS section, currently set to NONE, should that that altered to car maker's CANBUS ?

It is not the problem that it drains a ot but all small drains can pile up so eventually you have a problem. I have park mode security enabled on my dashcam system so it drains some, OBDII can drain a littl, but it is known that in some cases keeps ECU awake that can drain a lot due teh number of sensors it keeps awake also

All was ECU side due the different pinouts see my pics, I have seen in the past several USB -> COM chips that are not supported on Android due the OEM build and specific drivers like some factory that are not recognized on laptop till you install their licensed software (Usually JUNGO Based Drivers).

Only if you got specific cables with canbus decoder (black little box). even then USB OBDII is used to diagnostic and clear codes. I use Toque 1.83 and it works on one unit that v1.52 didn't worked with. Usually ELM v1.5 works better than v2.1

thanks! I have now got USB OBD unit 1.5 (still need splitter/extender), tried yesterday with Torque as well as with Palmer's DashCommand:
it kinda worked - during first trip, 45min, Torque app crashed twice or more, worked after restart, on return trip, DashCommand also choked once or twice, thenm I relaized, as fuel tank level is not reported, unless I run app 100% of the time, fuel consumption won't be correct - and, realsiticall, I need TomTom on the screen more than gauges....
I see there are OBD spliters that 'allow' two or three OBD devices plugged in, wouldn't you know, is it OK to split/use multiple OBDs ?
like, I have TomTom 'Curfer' OBD data logger - just logs 'quality of driving", thoiught to get splitter to log data, AND, if so desire, call gauges on screen ?
thanks for explaing CANBUS!
do you use TPMS tyre pressure units, if so, which ones ? my radio has an app to read such, wonder if it's worth it ?

I have connected my USB OBD. Torque not recognised device. How to check that Scanner is properly installed on android system?
OBD scanner is generic just like this:
https://www.amazon.co.uk/ELM327-USB-Interface-Diagnostic-Scanner/dp/B00IWLLX1Y
BTW I have MTCE with android 8.0 with KLD MCU.

Torque lite ain't work with android/usb, only in bluetooth mode.

I have torque pro so there is no problem there.
Any way problem solved. Bought Bluetooth version.
