navigation upgrade with entertainment package?

[aeroforcei]

I have the 2005 SLK 350. It has the entertainment package without the navigation. It says something about the command navigation when it starts. Is it possilbe to upgrade the system to work with the navigation dvd's? It is a lease so I don't want to spend a lot of money on it. Any thoughts are appreciated.

I've been to the mat with MBUSA tech support on getting the iPod interface kit installed. They tell me that it is possible to upgrade the COMAND system to include the NAV system but it is not possible to add the COMAND system (with or without NAV) if you didn't have it in the first place.

I think the cost to add NAV is around $1900.

Good luck.

If you have the Command package already installed, you can upgrade to a navigation system. Pretty pricey--about $2K installed.

I have a 2001 jag xkr, dvd navigation is out of date. Any suggestions for upgrade discs?
