I have a BMW 335i with z110bt.
1. my EQ resets after i shut down the car....why? can i just run a cable directly from my battery? what are the pros and cons of this approach?
2. i see that there are firmware updates for the z110bt and the z120bt. i find it funny that the z120bt illustrates that this firmware updates can be done for z110bt's with the 2010 software update....what does this mean? i downloaded both files and both files are named avicz110bt.....can i load the z120bt (2.003) firmware on my z110bt?
example:
AVIC Firmware Update 2.003 Released!
The latest software version 2.003 has just been released!
This software is for the AVIC-X920BT, AVIC-Z120BT (and the AVIC-Z110BT that has
been updated to the 2010 software.)
3. after the 1.001 update, my bluetooth is starting to have problems. when a call comes in, the music gets muted, but my HU screen functions don't work, like pick up and hang up, i have to use my phone to use the phone features on the HU.....
