Since I have been driving it more regularly and not the better half, I've noticed that I can receive all FM stations fine, AM is a bit weak, but the system does not save the stations in the display correctly half the time. And sometimes, if I save a station to memory again, it may or not be displayed correctly again once the car is turned off and then back on. Despite the fact the computer unit has been replaced (probably unnecessarily) in the past and the dealer uploaded the software to it (latest version they said) I'm thinking it might also be a software issue and not a material interference. Ever seen a similar situation and am I getting closer to solving this thing or no? Again, all help appreciated!
