Surely I'm not the only one that's run into this problem but I've searched a lot of these message boards and cant find too much info on my issue. I just bought my first Merc, a 2003 CL55 with 34,000 miles for under 40,000. So far I love it and sometimes drive it nowhere just to drive it, however, eventually I'm probably going to want to go places and use the navigation system. The problem is that it has the CD-based nav on it (and conveniently enough there was no bundle of 10 CD's with the car!) No big deal I thought if I'm planning to pull out the whole Command screen and controls and replace it with something all-in-one aftermarket (7" touchscreen Pioneer or Kenwood.) I know this could get expensive, so my question is this:

Has anyone with a pre-2004 CL (or any other similar CD-based nav system) been able to locate updated CD's? What years were they offered and how much were they? I've heard rumors from my MB tech that beginning of next year navtech is updating all of them, and even coming out with new CD's for guys like me...is this true? I've read on here that the constant changing out of 10 cd's is a hassle and many times things arent on their maps. With that said, has anyone changed out the whole thing with a DVD/Nav
double din unit? Obviously this requires some custom install but I'm curious to hear and see how it turned out and if you were happy with the look.

Sorry for the long post...any help would be appreciated!
