Guys, I have command problem, overtimes I turn on the Navigation it tells me that CD Error, I try to open and check what’s the problem then I faced something strange inside if any one have an idea why the belt specially the junction between point 4 to 5 is not connected, hope someone can feedback.

Comments please.

well that doesnt look right..

why did you open it yourself? Your car should still be under warranty. Just take it back to the dealer to have it repaired.

he installed it after the fact, it wasnt factory installed.

Yes as Mr.CitronC230K_03 said... I installed it by myself.. it was working fine I completed around 1 year with no problem at all,, but recently when I put the Navi CD it tells me CD Error , Please Insert Navi CD..

Hope Mr.Steve can help me and feedback about the unconnected built.

This appears to be a configuration SAT (select at test) jumper in the flex-circuit jumper. I have not de-engineered a Comand unit yet, but this looks like there is a jumper between pins 4 and 5, with a provision to measure and cut during test. I have no idea what this is for, but it was cut on purpose, and was designed to be cut after the unit is manufactured.

This could be for the AM tuner to tune 9 Khz for Europe or 10 Khz for North America. It might be to enable or disable an option for one market, like watching TV from DVD.

Is there anyone who has a service manual for these things? Can you buy one?

Well I joined Pin 4 with Pin 5 and I turn on the Navigation, I found that when I play copied CDs its not working at all at the Navi Drive, but when I removed the junction it works fine.
I guess this is an aftermarket way we can use to play an Audio Cds in Navi Drive.

you could play Audio CD's in the Navi drive. you just cant use the navi function with an Audio CD in the navi drive. ive played both burned CD's and store bought CD's in the COMAND head unit.
