The Nav screen says "Replace with program disk" after starting for 15-20 minutes until the car is nice and warm then goes to normal operation. I'm suspecting it's a bad solder joint of loose connection on a circuit board. Anyone else ever have a similar situation? Gotta get it fixed because I can't adjust the heater or ac with the screen blanked out. What is a new Nav computer gonna cost me? Anyone know? Thanks in advance.
