The factory fit VDO unit in my E65 3.0d SE takes about 30 seconds to fid
where
it is after leaving the UK on the Channel Tunnel train and arriving in
France
(Calais) - pretty quick as it usually takes me a couple of mins to get
used to
driving on the wrong side of the road - dammed foreigners!
It's all down to religion and the teamsters!
