Replace NTG 2.5 with new head unit?

[Miserablegit]

Having some issues with my command head unit on W164 ML. Turns on ok and nav works but no sound, I can’t activate logic 7 and it says media interface not available.

I’m looking at the possibility of replacing it with something else. I’m anticipating this isn’t possible for the following reasons:
The system is a fibre optic system with a HK surround amp, a tv tuner, rear seat screens and rear seat DVD player.

If anyone can assist I’d be grateful.
Thanks

You can get a connects2 interface that’ll give you the ability to connect to the gateway and amp and give you steering wheel control for a third party head unit. I’m doing similar tomorrow in the OHs “new” SLK with NTG1. The audio andcnav displays in your cluster display no longer work, but that’s sctually not a big issue.

I did try and replace the NTG2.5 in my SL and gave up as it means losing various other features.

Many thanks- I’d been looking at those but, like you say, il lose some functionality.
I could cope with no surround sound and having to set the clock by pulling the fuse but wouldn’t want to lose the tv/dvd for the rear screens and I don’t know if they depend on the head unit or not as there is a separate Dvd unit in the rear.

Well some good news.
I’ve removed the Command head unit and I can still get TV and DVD on the rear screens.

No visible fault on the command unit - will have to get it tested.

You could always call Comand Online in Surry. They know all the ins and outs. Well known in MB forums.
