VW Golf "Nexus 7 HU" Install
Hey guys, been a long time reader but haven't had a chance to join. I just recently finished installing a Nexus 7 tablet into the dash of my car. Over all it wasn't that difficult of an install, however it did take time like anything worthwhile. :happy:
Here is the install..
Finally got to taking apart my dash and replacing my MFD2 with a Nexus 7. Lots of fabrication but it went together smoother than I anticipated. It has been a couple days with playing with it in the car and I'm very happy with it.
got the back plate covered in suede so it looks nice with the tablet out of the car.
The wiring is actually quite simple "idea wise". I got a Logitech Bluetooth Receiver with RCA outs designed for "home use". I found a car charger with an appropriate adapter at Radioshack that meets the voltage and amperage requirements. I wired it in to a 12 volt ignition on source with an (add a fuse). I buttoned up everything and it ended up working out perfectly.
I decided on not running a power wire for the tablet. There was a few reasons for this. As of now the Nexus 7 does not have a compatible car adapter, many USB outlets trickle charge it and end up displaying "discharging". You can short the usb outlet and end up displaying "charging". However I wasn't willing to go through with the hassle. Not to mention different USB outlets have different charging rates depending on the length of the USB cable. The idea is to keep it as short as possible.
Regardless I think the tablet has plenty of battery life for my day to day use. For extended road trips I can easily remove the tablet and charge it in the car with a power inverter. But I'm sure an easy off the shelf option will be available soon. There are rumors of a dock connector possibility for the tablet so I will keep my fingers crossed for that.
As of now I can get the tablet to emulate as if it is getting an ignition on source. This is done by the android app tasker. I Have "tasker" set to turn on display when Bluetooth is paired. Since I wired the bluetooth module into a 12 volt accesory outlet it turns on and off with the car. Then I set "tasker" to turn off the display 7 seconds after a bluetooth signal is lost. It ends up working out perfectly.
If you guys have any questions feel free to post them up. I will try my best to answer them.
