avic d3 2004 c class benz

IS there any real difficulty doing this in a 2004 C-class mercedes. (i.e. could you help me find the vss. which wire is for the e brake if its an electric one or not.

what model C class is it? rtfm

there actually is a single din dash kit for the car.... my shop did one and just used the metra kit as a template to build a d-din dash kit... dude.. honestly nobody uses vss with pioneer nav units and u really don't need it... but i think thats a can system anyway so an interface may be needed short of goin to the transaxle or bcm for the vss..... and another thing..... parking brake??????????   lol... i applaud your commitment to installing the system as the manufacturer suggests...integrity is a big problem in the world rite now....  if it is a regular audio system in this car i believe that metra also has the harness too...i wanna say 701784... doesn't help to look it up i guess... and it's got a diversity antenna that will need to be powered up too....there can be only one.......
