had to get my radio switches replaced today, and on the way home I noticed that the gps seemed to be loose, and vibrating. looked further, and it does not appear to be attached in the front at all. I can pull it up a quarter inch, easy. Is there a lip or a catch that is not set correctly? How much plastic do i need to take off to fix this? or, just take it back to the dealer, since they messed it up!
