Replace / Repair ?? Comand unit (NTG2) on W203

[AirScrew]

Any suggestions on a way to cost effectively replace my COMAND unit.??

Short story is, one day last week the NAV would not boot, screen and logo came on, but shut down after about 20secs.
Then repeat behaviour.
2 days later the car would'nt start at all. Nothing.
Infact the battery was drained down to 4v (yes 4v).
Fresh battery and left overnight (car locked etcetc) went from 13.4v down to 12.2 in 10hours.
Took it to an auto elec specialist, who tested and found the drain to stabilise after 10 minutes at 1.1A in 'locked' mode.
Tested/pulled a few fuses and found pulling the COMAND fuse took the parasitic drain down to under 0.1A and dropping.
Normal levels.

So, not only would the COMAND unit not power up. It was shorting and draining the battery. That was yesterday.

Its a high mileage 07 W203 model, so paying alot of money is pointless.
Going to a main dealer is out of the question ofcourse.
Any electric wizards out there.??

Does anyone have any experience on where/how to repair the NTG2?

Any advice/experience on getting and fitting a second hand unit?

Thanks in advance.
J.

Yup, you're looking in the right place, richard can help, but keep in mind that 'cost effective' is subjective.

@richard or @Alfie at comand.co.uk are the people to talk to, have your VIN handy so they can look up the build sheet for your car. They also supply and fit aftermarket units like Pioneer - they're close to J3 M3.

Its not necessarily the comand unit causing the drain. It could be any device connected to the Comand.

Hi I’d like to join in with my similar problem. My W203 has a NTG2 and it’s started asking for the navigation disc to be inserted, despite being removed / reinstalled, removed cleaned on trouser leg and reinstalled it still asks for the disc. Is this a recognised easy low cost repair? (haha). However rather than put £00s into fixing it I’d rather spend extra on getting something more 21st century. Anyone with what the cost of a ‘kit’ with say a pioneer head unit inc the req adapter bits? Am I right in thinking the NTG2 has fiber optical things which present problems when replacing it with something off the shelf? What about the NTG2.5? Sorry about the number of questions.
