Hello.

I have a problem with my 2009 Mazda CX-7 BOSE System.

I couldn't switch to Sat Radio and to AUX modes using buttons on stereo it self, and also it's not working when i trying switch it from steering wheel using 'mode' button, disconnecting battery didn't helped all, any suggections how to fix it?

Thank you!!

 

Just a suggestion but have you checked your preferences? The radio also has an ID. Your owners manual tells how to check these.
