ATTN: Mr. Gilley
Been getting estimates on DVD nav conversion system for my 01 ML55, i.e. one DVD disc for entire United States. Understand the DVD nav system in question came out by MB in 2003 and can be retro-fitted in earlier models, including my ML55. Anyway, the local MB dealer has told me I need module #Q-6-82-0701 and retro-fit kit #Q-6-82-0700. I have been told by another DVD Nav sales source that the correct module for my vehicle is #Q-6-82-0821 and the retro-fit kit provided by the dealer might be correct. I need to know with certainty which module and retro-fit kit is correct. Can you help?
