Hey all. I've got a 2012 Canadian STI with the X9310BT installed from factory.
I've previously updated to the 2013 maps with no issues.
I followed the guide here to update my firmware last month, and the maps work great, however there's numerous glitches with the audio / entertainment. To list a few:
iPod is detected but won't start playing music
Aux-in no longer works
Playback from SD card takes several power cycles of the device before it functions
Bluetooth audio and handsfree calling no longer works (both before and after BT firmware update)
If there's any further info I can give
