Hi,
I have been following this topic and have installed the unit I have purchased from Ray this week.
Has an android mobile user opposef of the majority here (Iphone users) I beleive my experinence can bring some added value to others:
1) Installation took aprox 3 Hours, I had already whatched all the videos posted in page 3 of this topic, they cover all the situations and it was not a bad experience you just need a little patiente.
2) Unit is a great improvement over the OEM one and the finish aspect looks smart on the dash of your car.
3) I bought the unit mainly for navigation purposes and YouTube audio/video access, as well as android auto integration.
4) with a third party application i was able to setup Android Auto wirelessly with my samsung phone it works like a charm, connecting the bluetooth to the car and the wifi hotspot to the unit, android auto works perfectly, calls are routed via the oem bluetooth using the oem mic and speakers , but all notifications still appear in android auto.
5) The bad:
A) The unit only works with your car ignition on, meaning if you are parked and want to see some youtube videos or listen to music you need to turn on igniton, the OEM system does not need it.
B) The audio buzzing, already discussed in here an yes it's annoying but not a deal breaker.
C) Google maps navigation instructions, for some reason this is the only app where the external speaker is used, i wish i could use the car speakers. Seems the audio is first routed from car speakers to the external one because i always ear a bip through the car speakers in the beginning of the instructions but then it switches to external speaker. Maybe someone already found a way around this?
D) Fingerprints: with the screen off there is a lot visible, but once on no issues.
Overhall I'm a happy customer, I would buy it again even knowing the 4 issues above that for me are the most annoying ones, for issue c) alternative is yo use google maps in Android auto but visually is not exactly the same.
Regards,
Helio
