Hello everyone,

I have a 2006 Mercedes SL500 Roadster. The COMAND nav system is crap! It's the software DVD which even if you buy the latest has huge areas without mapping. I live in WA. & only major roads are mapped. Anyone know if this system can be upgraded just use the screen & sys unit but run in better software?

For a car that was over $100k new I use a TomTom. Looks ridiculous but it works.

Any idea, suggestions would be appreciated,

Thanks,




I didn't find the right solution from the internet.
