All the things you describe mine does the same exact thing! However I do not have the updated maps. I need see my firmware was on 13 so I was hoping this was the issue. Everything else on the unit acts how it should for me... It is just the Nav. I am going to contact the the shop. I actually have a Clarion NX602 that was pulled from another car of mine. I am thinking of putting this one in and sending the Kenwood off to be repaired. I prefer the kenwood but man!!! Shame on them! I have never had an issue and have always bought their high dollar units and this clearly is an issue across the board on these. I really like the sound stage and eq on it so I want the unit but operating as it should as I use Nav alot and it has been rendered useless.
