Hi.. I have a 2003 ML350 OEM radio that kind of works... when it turns on it works fine, but then you maybe can't turn it off... sometimes you can turn volume up/down and sometimes not.. maybe the actual on/off knob itself?
I'd just junk it if I didn't think it was reparable or maybe someone can use parts off of it... screen works perfect.. all the buttons and knobs are there and functional.. it just has intermittent power and volume.
I am willing to donate but you either have to pick up in person or pay the shipping.
The Part # on the sticker is: A 163 820 20 86 Model: MCS Model #: NV4BN110
