One of the entries in the Jailbreak Appradio2 thread identified that there was a new firmware for AR2 out.
Followed instructions and have version 8.15 loaded on my AR2. Fixed my iPhone contacts list and functionality now all works with the radio running.
Don't know what else they fixed. My FM reception still sucks.
Easy to do. Just followed the ODF instructions.

It states that's it's for USA And Canada. I'm from the UK ...Is there one out for EURO ?
Found it ......thanks..
Seems like the only improvement is : "Rear view camera stability improvements"
I ain't installing because I don't have a rear view camera .... so no Point .... 
I had a problem with iPhone 4 contacts and phone lists not working - or showing up and being erased immediately if the FM radio was on. Only worked when the radio was off. Someone suggested it was a bluetooth issue. This firmware fixed this issue and the phonebooks are there now even when radio is playing.
I had/have same problem....phone Bluetooth contacts and presets when selected, appear then disappear to "unknown" when radio is selected....they work fine if no radio on or using IPod music feature.... I did the update and still the same thing.....anyone know of a fix?.
Using an iPhone 4
Same problem here, when radio is running my contacts dissapear, when radio is off contacts show up ok. Please help, running Appradio 2/iPhone 5/V8.30
