I have a Golf 7 with an OEM auxiliary heater.
Is it possible to turn on the heater with android or adjust the heating timer?

alot of engine noise and hissing noise even when car is off
its a nexus 7 timurs rom, sound going from nexus via 3.5 tapped into factory cd changer any suggestions?
Ground loop isolator.......
I just solved this problem in my own installation. After some searching around, I ended up deciding on this:
http://www.amazon.com/gp/product/B001EAQTRI/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
It's a good price, free shipping with Amazon Prime and completely eliminates the alternator whine you're experiencing.
Thanks i ordered it from my experience in car audio ground loop isolator a while removingr whine also make the sound dull
Maybe i am wrong but it doesnt seem like a proper solution
Maybe grounding usb power? Or the 3.5 mm jack on the nexus to the cars body?
Who said you had to use one in the audio line?
If you know what to look for you can isolate the noise in the power supply line itself.Something like this. Now the real question is why is it hissing even with the vehicle off. In reality it shouldn't do it at all but nothing is ever perfect and trying to track down a ground issue can be more trouble then it's worth. Do you have battery drain issues? or low charge or possibly high charge while driving? Wondering if you have a possible problem with the voltage regulator in the car itself. When they go back they can actually cause a draw with the vehicle off. Doubt that is the issue but figured I would ask.
And just to be clear as to what you are doing. You are going from the Nexus (headphone jack) to the front of the stock car stereo(AUX input 3.5 jack). Do you have the tablet plugged in to a cigarette adapter or charging by any means via the car? If so, have you tried having it not plugged into the charger to see if that changes anything? Most cigarette or power adapters are not isolated so if you use them you have the possibility of it happening.
Why is it that every android phone I've had has a hiss that comes through the car's speakers when listening though the cars auxiliary port and charging phone?
This has happened with every android phone and every car it seems. However with my iPhone's it doesn't happen. I buy quality charging cables such as the Griffin brand.
Does the sound level of the hiss go up and down with the rpm of the vehicle? Cuz if it does that would mean you have been having a grounding issue

Coming from a developer edition M8 that I converted to Gpe....I purchased the 64 GB Nexus 6 from the Google Play store last week. Everything works great....except I hear a lot of EMI/Power noise when connected with a 3.5mm aux into my car stereo while the charger is plugged in. It is especially prevalent during any screen activity. The M8 had no such issue. I've taken the following troubleshooting steps:
1. Replaced the aux cable with a better shielded one.
2. Tried the supplied quick charge adapter and cable (my car has a power inverter built in).
3. Plugged the M8 back in with the above and didn't get any EMI.
The noise is present whether I am streaming from Spotify, Google Play, or playing Non-Streaming local media.
Has anyone experienced this kind of issue? Should I get an RMA from Google?
I love the phone so far....
I doubt you'll get any satisfaction from an RMA. My experience is that car radios are EMI nightmares, in that it really doesn't take much to trigger it.
You say that this is with the phone plugged in to power? As in, it is *NOT* present when it is running on battery? Car electrical systems are *incredibly* noisy. With a high voltage spark ignition system, it is no wonder at all!
In fact, for car audio enthusiasts, there are lots of special devices out there for handling this kind of noise, especially when dealing with amplifiers (which amplify the noise as much as the music!).

Note that there are filters that clean the AUDIO line, and also filters that clean the POWER INPUT line.
*** This EMI noise does NOT indicate that there is a fault in your phone!

Yes....if I remove the power cord, the EMI goes away. Perhaps the Nexus 6 is just more susceptible to this kind of interference.

That's... pretty much what I said. I also explained why, and what you can do to deal with it, i.e. by installing filters.
Didn't read your post thoroughly, but you might have some ground loop problems. This happens whenever I have anything feeding audio into the aux line in my car that is also powered by one of my car's power ports. Try a ground loop isolator from Amazon and see if it solves it: http://www.amazon.com/PAC-SNI-1-3-5-3-5-mm-Isolator/dp/B001EAQTRI/ref=sr_1_1?ie=UTF8&qid=1434054047&sr=8-1&keywords=feedback+isolator
Hi.
I am finishing installation on my Nexus 7 in my car. I use the DAC Behringer UCA202.
There is a constant and strong noise... I was reading that it can be by charging tablet...
Please, anyone can help me?
Thanks
I was reading about this. It seems problem about ground while the tablet is charging.
Some solutions...
USB filter
RCA filter both, seems that there is a loss of quality of sound.
and any other?
Experiences???
Hi, it's a ground loop issue , i've installed my nexus 7 in my car, i removed the battery from it and use the 12v plug with a 12v to 3.7v converter, to get ride of the hum noise, i had to diy a ground loop isolator for the audio jack (but you can buy them on the internet), the hum/buzz sound is now gone.
The quality is good but the real issue is that i lost some of the bass, i don't remember clearly how much, i should try without it tomorrow to compare again, but i still enjoy my music .
The other possibility is to use à dc-dc isolator supply, but they are expensive (+100$)...
Hi, ground loops car caused by different potentials because of ground points that aren't the same and current flow that is picked up as noise.
My suggestion would be try an isolated 12V - 5V power supply. Those shouldn't be expensive and you can likely find some on eBay. There's a very high chance that will resolve it permanently.
Just needs to be capable of the current draw for the tablet in use & charging. If you're also using a hub and so on you could add second power supply as well.
i toyed around with passive usb isolators off ebay. cant tell if sq is any worse other than the immediately lowered noise floor with the hum gone.
As Marty mentioned, the problem is that there is a voltage potential difference between the amp's ground and the ground you are using with the power to your tablet. The passive power isolator/filter is easy solution if it works well enough for you. It won't deteriorate your sound quality, except that it may not fully eliminate the noise. A filter in the audio cable can cancel the noise, but it will also cancel certain frequencies in your music and affect sound quality. The "most effective" solution is to physically connect the amp ground to the ground you are using with the power to your tablet. That requires getting under the dash, finding the ground wires in question, and jumpering them. Or something similar. Hope that makes sense. But if a passive usb power isolator does the trick for you, then that's the "easiest effective" solution.
There are line-level (RCA) ground loop isolators that have excellent sound response, but they're not the cheap ones you'll find in a stereo shop or electronics store. They're $50-$100 but you can find them on eBay at times.
Jensen and I think 1-2 companies make some with great fidelity. But if the USB isolator did the trick, that's excellent. The ground is the problem, after all.

I did this, bridged the tablet ground and headunit ground together. It reduced the hiss, but it’s still noticeable especially when the engine speed is high.
I guess the next stage is to try an isolated power supply!
Can i charge my mi Outdoor Bluetooth Speaker from my mi note 5 pro phone's charger (charger rating- 5V/2A).
But input voltage rating mentioned on the back of speaker is 5V/1A.
.
Show tell me can i charge it without tention.
Yes you can use it without any problem
