No sound from MCS
Hi
I finally got the security code to my MCS (2001 ML320) and tried to use it briefly. A couple of issues came up:
- No sound at all, on tape or radio (tried scanning as recommended by MB, still nothing). I tried turning the power knob in both directions but there was no visual (on the screen) or sound effect. It works for turning the system on and off.
-When I select 'CD', it tells me 'No CD Player installed' but there is a CD changer in the back which works as far as unloading and loading discs. Also, are there some easy solutions for things like AUX/Bluetooth?
-This isn't overly important but how much trouble would be involved in getting something out of the NAV and Phone features? ( Both currently saying 'No navigation system installed' and 'No telephone installed' respectively)
Any help would be appreciated thanks.

I think I'm gonna need a little more help :/ Is there a guide somewhere (with pictures) I can follow to find/remove/modify things? I'm comfortable with taking stuff apart (and putting them back together!) so I just need some instructions. This is so I don't have to ask you every little question. Thanks

What is it that you need to remove?

Sorry I completely forgot to say something here. I got a replacement MCS unit and the sound worked. Then I tried the original one and the sound also worked. So I think I must have fixed whatever wiring issue was present during the re-installation. I've been using it without any issues since. Thank you for offering to help though
