Thanks all of you for a great forum
As I am not able to find exact answer in previous threads I will like to try a new one.
Recently I fitted a command 2.0 (210 820 54 89)in my E220cdi T 1998/1999. in exchange for the original Mercedes 30 radio with cassette and remote cd-changer and telephone. I had to rewire the plugs a bit and install a GPS antenna (under dash original Mercedes), replace the plastic frame and wood panel.
I have updated the comand unit with MY2001 software(yes from the cd player that now tells me there is no cd installed and returns the cd when I feed it ??) .
I have also altered it to no can bus, according to instructions from a German guide.
However the only things that seem to work are:
Radio, cd-changer and telephone.
No navigation and no cd function (internal).
I have replaced the laser eye, without success.
I have the following error code(s) present:
B1762.
Also B0017,B1736/2 and B1736/10, but they did not come back after I deleted them.

My next step is to try to configure it at a Mercedes dealer/shop, hopefully this week.

Any suggestions out there
