Help with MCS/NAV Retro Fit

2208 Views 8 Replies 6 Participants Last post by  Benz-ene
Hi guys,

OK i got my MCS and NAV retrofitted into my 99 ML320. I got the anntenna, all the cables and adapters, and the CANBUS adapter installed just like the directions and photos. It turns on, finds satallites and gives me routes and so on...

The problem is, on the map it shows where i am, were i am going (a bit choppy as i drive along)but it doesnt give me voice commands or visual commands of when to turn, and also the time to go and distance to go does not update itself...what did i do wrong? anyone else have this problem with the retrofit?

any help would be greatly appreciated.

Did you ever find the problem? Was it the VSS like Ian mentioned?? I am having the exact same issue. Thanks

Can you please describe step by step what part you purchased and what part you installed and how you installed it?

Without such details how do you expect us to help you?
There are at least 20 points of failures here.
