I have a problem with navigation / map. When i zoom in (scale 200m, 100m) map freeze, it stop move/rotate. I have to lock/unlock car to start working again. If zoom/scale is bigeer than 500m map is ok. When map freezed, dashboard info for navigation is continiue working, only comand map stop. Other functions of comand are fine(audio, video).

Any idea?

Have you checked the navigation DVD for smudges/scratches?

Last time I had my E350 in for service the nav was acting odd after it was returned.
Ejected my 'backup' nav DVD and found it covered with greasy fingerprints...

Old topic but any updates? My SLK does exactly the same. It's not the map-DVD because same problem with original 2004 DVD and same thing with 2016 "backup" DVD from Ebay.

i had this problem on the dvd nav of my w211 in the trunk. Burned several discs changed them for original still got screen stuck on losding dvd map navigation activated.

i fixed the problem. I opened the dvd housing and cleaned the lens with a cotton earpick. 5 min job. Then i put it back and guess what. The maps updated in command to latest version and them i had a fix.

its the dust on the glass lens !

get it clesned and save urself headache and 100eds of dollars.

Could you Maroc please tell more detailed how did you get into the laser lens? I removed top cover but was afraid of remove more fragile parts of the DVD deck. I managed get the soft-top-stick into something I believe lens or similar. Then I gave little bit pressurezed air. Didn't work. Still got jammed & rebooted when scaleing up. Good thing is that it still works like it was. Nothing more broken.

I'm just thinking did I cleaned reading lens or plain laser emiter.

yes that i did do

So you did not took apart anything else than top a cover? No unbolting any parts of DVD slideing deck system?
