Hi All, I've been lurking around this forum searching for the right solution for my MKIII, but no luck. Various answers but can't find a difinitive way to fix my problem without paying $2k for a new unit.

My MKIII (MY02) has been acting up lately, it'd display "no disk" even though the disk is in the drive, keeps rejecting my disk, and seems to only work half of the time. I've been told it's my battery (never changed since I bought the car), loose cables, exterior temperature, and corrupted firmware.

I will take my car to get the battery re-charged next week, but I haven't been having any problems with starting my car at all, so I don't think that's the issue. Also, the nav would work at times, so I don't think it's loose cables or bad firmware, but I could be wrong.

Can someone provide more insights into my problem? It seems that a lot of people have been encountering the same problems I have, but no real solutions (at least I can't search in the right way to find it). Let me know, thanks in advance.
