What is the BT echo problem? I drove the car today and while streaming Pandora, it would kick the phone connection on almost every song...Just installed v70.00.100 NA N today, used the zip MazdaToFiatV70 confirming ID7v2 worked.
Then installed the hardware and confirmed Android Auto worked.
Then v70.00.335 that fixes the BT echo, used serial to hack it ID7 Recovery v2 and installed the Fiat zip again, and a few tweaks.
So far so good, thank you guys!
Never did that before.
