A couple of days ago the Navigation system stopped working. It would come on for a little while . . .then stop working . .. then come on for a short while . . .then stop working again. It has been intermittent. My mechanic says there are no loose wiring connections and that it's the unit. I trust this guy but I went looking for other advice. It has been suggested that maybe it's the power supply.
Before I go and try to replace the unit, I'd like to make sure what the problem is. It's important not only for the GPS but it has the radio, CD and phone which I like.
Does anyone have a similar experience with the Navigation system cutting out intermittently? Any advice would be appreciated.
