Retain the factory USB socket in your Mercedes when replacing the factory radio plug-and-play adaptor covering 15 Mercedes models from 2004 to 2018.
The Stinger MTAXMBUSB is a vehicle-specific USB retention adaptor for select Mercedes vehicles, allowing the factory USB socket to remain functional after the factory radio has been replaced with an aftermarket head unit. It connects the factory USB socket wiring to the rear USB input on the aftermarket head unit.

Goes Well With:
Does my aftermarket head unit need a rear USB input for this adaptor to work?
Yes. The MTAXMBUSB connects the factory USB socket wiring to the rear USB input on the aftermarket head unit. If your chosen head unit does not have a rear USB input, the factory socket cannot be retained. Confirm your head unit's rear USB input availability before purchasing.
Despite the title saying "BMW/Mercedes," does this fit BMW vehicles?
The compatibility list for the MTAXMBUSB covers Mercedes models only — no BMW vehicles are listed. If you need a USB retention adaptor for a BMW, contact the F.A.E. team to confirm the correct product.
Is any cutting or splicing required?
No. The MTAXMBUSB is a plug-and-play adaptor that connects to the factory USB wiring without cutting or modifying the factory harness.
I have a Mercedes Vito — should I use the MTAXMBUSB or the PC7-AUX-MB01?
It depends on your Vito's generation. The MTAXMBUSB covers the Mercedes Vito W639 (2007–2015). The PC7-AUX-MB01 covers the newer W447 (2015–2019) and also retains the AUX socket in addition to USB. Confirm your Vito's chassis code before purchasing.
Does this adaptor fit all Mercedes models?
No. The MTAXMBUSB covers the specific Mercedes models and year ranges listed above. For other Mercedes models not listed, contact the F.A.E. team to confirm the correct USB retention solution.
