I just got a sienna with an AVIC Z130BT installed. When I test drove the car everything seemed to work fine.

 

However since I got it, it hasn't been working.

 

It says the GPS reveiver is disconnected. the mic doesn't seem to work at all. The steering wheel buttons don't control it.

 

 

Could there be a simple fix for this?

 

My dealer told me before I bought it that he is not warrantying the unit so there isn't much use asking his help.

 

 

Is it possible that while he was working on the car he did something?

 

Thanks,
