Comand works by itself but not links to the car
Hi:
Car is MY04 R230 SL350, manufactured in June 2003.
My Comand’s LCD screen got bubbles and whitened background. I then happened to find a JP version Comand. I tried to replace it but it didn’t fit.
But that’s not the problem. The problem is when I put back my original Comand, I lost “waken up by ignition” function and steering wheel control.
Symptoms:
- Comand can be turned on by pressing power button. But won’t turn on when ignition is to be turned on.
- Likewise, Comand won’t shutdown when ignition is turned off. I must manually press power button to turn it off.
- Steering wheel controls don’t work.
- Instrument cluster doesn’t display track info. The audio menu is showing “--------“
- No malfunction msg on inst. cluster
- Able to manually play CD, AUX, FM/AM. But it shuts down every 15 minutes.
It seems that Comand doesn’t recognize my car. Especially the behavior of shutting down every 15 min makes me think that Comand is unlinked from my car. At least it doesn't know my car's ignition status.
As you guys may already know, we can turn on Comand to listen to music while car is off. But it only allows certain period of time. To use it afterwards, we need to turn it on again.
Any thought on this? Is there some kind of required mechanism that involves configuration by computer whenever Comand is disconnected and connected back on?
Thank you in advance for any input.
David

LOL...
Just figured it out. My C2 connector (which contains pins for CANBus communication) was not firmly plugged into the socket.
It needs to be inserted in certain angle and must be inserted very hard.
It is recommended to have another person holds Comand unit for you otherwise it is easy to ruin the leather around it.
Best regards
