I know this gets asked all the time, but I'll have to ask again. Is it possible to add navigation (dvd nav is preferred) to an ml 320? Does it require replacing the entire MCS? What about any additional wiring to the antenna or other unknown things that might need to be done? Is this doable and at what cost?
If anyone has even an educated guess, please let me know
Thanks

 

yes... can be done.
no...you dont have to replace whole mcs.
