i got my radio code from dealer,after putting in 5th digit the first number flashes.even after entering OK. After a couple of trys gets stuck on WAIT & locks out again. , HELP!

You might need to pull the radio and get the serial number located on the bottom of the radio and have the dealer get the code off of that! I had the same problem, but I need to replace my radio.

try resetting the ECU by disconnecting the negative battery cable for 15-20min or so. Then re-enter your code once the radio comes up. Youll have to re-cal your ABS/Traction (steering wheel lock to lock a few times) and cycle the window motors also. If it still isn't working, it's a fault within the radio itself and needs to be looked at.
