Hi guys hopefully someone can help,
I have a 03 Zed with the Bose sound system sounds good and doesn't jump tracks in cold weather but the buttons on the Head Unit don't function apart from the volume,on/off and the both eject buttons (one for the CD and one for the cassette)
You can however use the steering wheel controls to change tracks/radio stations depending if the radio is stuck on CD or Radio function.
Hoping it is a simple wiring issue as I would like to keep the standard look for now.
