This is actually very weird. I recentley received my unit back from Pioneer (Had it fixed) but the one of the issues is still present. I am wondering why ...

 

The problems is that the ADRESS SEARCH is ALWAYS grayed out. And when I try to get GPS guidance by pressing on some point on the map, ti tells me ROUTE CALCULATION WAS NOT POSSIBLE. Even if I click somewhere right next to where I am.

 

What could this be ? Avic is properly installed, and brake wire is properly connected. I have another barain unit, should I try to switch them ?
