Hi,
I have the AVH-8400BT in my Focus ST. Today I finally installed the App Radio cable and have that all working pretty nicely - having had to downgrade from iPhone 5 back to iPhone 4s to make use of my spanking head unit!!!
Anyhoo, I've been adding apps n stuff to take full advantage, and I thought since I've had this headunit since September 12 maybe I should check for Firmware updates....
I see there is one available, however (luckily) I managed to spot posts on the net where people have updated their firmware and it has bricked their bluetooth modules on the headunit...
Quick
