After fitting a new cd player in my mercedes vito the speedo/odometer stopped working. The connection into the speedo seems ok, all the fuses are ok. Any ideas? Where is the sensor located?

You've been working in the vicinity.
Must have disturbed something.
Take the radio out again. Does speedo work?
If so, fault is the radio. If not read line 2.
If not, it's incompatible somehow (unlikely)

The standard M/B radio has a speed sensor signal fed into it.This allows the volume to change slightly with
road speed.If a different radio is fitted ,then the speed sensor wire must be disconnected otherwise you will get problems with speedo/odometer.
