W211 Comand APS Questions
Reading through various threads and having had a Comand for a few months I'm left with some questions.
In older units there is a service menu and a hidden menu within that. I know the hidden menu was removed in later units but is there still a service menu and how do you access it?
How does calibration take place in this unit. I read about calibration in other units but the W211 Comand APS doesn't seem to have any menu options. Is it only carried out automatically? When I first installed my Comand unit the map was about 200m out when I took it for a 15 min drive (despite 6+ satellites) Next day it was spot on. I just tried a 2008 v8 DVD and initially it was running about 40m out for about a mile then gradually improved. Today it is still 10-15m out and it is really annoying me. I don't understand why a GPS system should need any calibration - GPS is an absolute location.
