Are W210's prewired for Nav system? Has anyone done a retrofit?

Thanks

No The W210 is NOT Prewired for the Comand....Connectors changed/speed signal wire added and the cage in the dash MUST be replaced
Its not a simple install...Dash/console/front seats and carpets MUST be removed for the install
Some can get the replacement double din cage in without the dash removed..its a LOT of work!
Also a antenna must be added..or a splitter installed

This may help you understand how much work is required

HI I did instalation myself on my car and i did not removed seats. just front console all the way to the arm rest. wasn't that dificult hardest part was to take old bracket and to put new one in. If you have right hardness kit it's just plug and play. Thanks hope helps
