I have a d3 and the navigation was working fine. then i took the radio out for a wile and wen i put it back in the navigation wont let me search for places or for a address. It wont let me fix the clock eather. The only thing it will let me do is go to the addresses i have programed in it. Anybody know what could be wrong? i ordered the new 2010 navi dvd to update it and see if that will fix it.
