i have a roadmaster VR3 VRVD640G 4'' navigation dvd player.
i recieved my unit from walmart.com. installed it and it sounds great.
when i press the navi onscreen button it hlghlights red and you hear a click but it does not load. so i called road master and they sent me out a new unit. brand new unit out of the box. installed that unit, same issue. i called road master and contacted a supervisor and told them the 2nd unit is still having the issue. over the phone we checked all the wires . nothing seemed to be wrong with my installation or antenna.

they will be sending me out a new unit on monday.

has any one had this problem on their unit? the antenna isnt kinked. and everything else works fine. its almost like the aplication isnt there.
