2001 SLK 320

This will work but you need to cut the RCA gray and white, separate them and wire directly to the head unit wiring.

Perfect for Mercedes E320 2001

First glance and I thought "oh no this has been wired wrong". However that is not the case and it works perfectly with my E320 and Jensen VM9314.
Note to E320 owners. You need to tap into the black/yellow wire (switched power) from the cigarette lighter as Mercedes does not have it in their stock harness. Just remove wood panel surrounding the gear shift. Remove two screws holding ashtray. Put shift in reverse so you have room to pull out complete ashtray assembly. Then just unplug the power harness from the cig lighter and you have clear access to the wiring. Quite simple, really. Do this first and you have lots more room for radio installation also. The RCA-style speaker connecters totally make the wiring process simple. Go to posi-lock website for easiest connectors you will ever use. Sonic shipped all my gear in less than two days of ordering. Thanks Sonic!

Aftermarket radio installation

I purchased this wiring harness to connect the aftermarket radio RCAs to the factory car amplifier. Works great though the plug is a bit tight.

Metra 70-1786 for a 2006 Chrysler Crossfire w/ Infinity factory amp!

Product worked great. It is a must have if you are doing a replacement of the factory radio that has an Infinity stereo system with an amplifier with an aftermarket radio. Was an easy swap!

required interface for European cars

works as intended and makes installation of the new receiver seamless.
Not cutting of wires is needed so installation is straight forward.

Just what the Installer spirits ordered. Needed for you Mercedes!

Seems that this is to keep your factory amp(s) and have more musical ability than factory. Quality made, no wasted money though.
