Hi, I'm a new member and I have a problem I can't seem to solve!
2004 E320 CDI
The problem: The head unit displays the following message, "software update" with underneath two empty loading bars. It always and only shows this message, there is no response to any input. I have the original dvd. When i put it in, it spins it for a second and spits it out.
Solutions according to google: 1. put in the disc (which it spits out) and press 3 5 7 2. put in the disc (which it spits out) and press 1 3 8 3. take out fuse 6 in the rear fuse box, this should turn of the system. (i took it out but the system stays on. Discovered that fuse 5 in the front box does turn off the system, but it comes back to the original message.) 4. I also tried putting the disc in the rear DVD player... out of desperation. This one works fine but apparently is only for map discs. please help
thanks :
