[MTCB Android Head Units Q&A] marco.lav:
Hello everyone

I installed Android 4.4.4 on two UH

I get the following results:

The first stereo (GS) I installed "KLD_4.4.4_800x480_141208_rooted_light_reparted_init.d_v4.1.zip"

Version of MCU 2.08

result:

- I can not connect the adapter to the stereo OBD.

- The knobs for volume and tuning manually do not work well. (If I turn a knob to increase volume, the volume starts going up and down and goes a little crazy. It's not stable.)

on second UH

Version of MCU ( not remember the number, the date is 16 november 2014 )

on this UH all works good.

on both units, there are problems on the AF function of the radio data system

in Italy there are many bridges and tunnels, and then the frequencies of the radio change very often.

The AF of the Radio Data System, if it does not find an alternative frequency for the radio station I'm listening, it will tune to another frequency, but more research station that I was hearing.

Are forced to manually find the radio station I was listening.

I think it's a problem of MCU or radio chips, anyone can 'give me a hand.

attack two videos that show what happens.

I hope someone give me an answer otherwise I commit original stereo :(

(change station at second 2-3)

// add url of map and Frequency changes in 34 KM

my idea:

-1) Has to change the station only if it finds the same radio (in my video is "RDS" italian Radio)

-2 Tunes to another station, but research the radio that i was listening, when it finds the retune my favorite radio station.

- Along my journey from Brienza to Potenza (and vice versa), the single radio station I listen to is broadcast from three different frequencies as I'm driving because there are so many mountains and valleys here in Italy (and each valley is covered by a different frequency for the same radio station so it can be heard in an optimal manner). Therefore it is very important that these alternative frequencies are found on their own by the stereo, even after a long while. Here is an example of what I mean: I'm driving and I reach the first tunnel in the photo (black). As I enter the tunnel, I no longer receive my radio signal or any other radio signals at all. When I come out of the tunnel (roughly 1 minute after entering it) the Unit Head tunes into the first radio station it finds and NOT the one I was listening to before entering the tunnel. The Unit Head should find the radio station I was listening to before entering the tunnel, on its own. If the Unit Head does not find the radio station I was listening to before entering the tunnel, at most it could find another radio station and let me hear that while it continues to scan for the radio station I was listening to before, but this does not happen. Usually what the stereo does is: if it does not find the station I was listening to before entering the tunnel, it finds another station and stops there. It does not remember the station I was listening to before and does not keep trying to find that one. This aspect is extremely important here in Italy

Is anyone able to give me some help or some suggestions?

thanks a lot
