Easy to Install and Works

Written By Kevin, California on Thursday, November 12, 2015

Crutchfield Customer Review (What's this?)

Pretty easy to wire, instructions are clear, and does what it is supposed to do. Only thing I would ask for is a smaller footprint on the chimes box and also maybe shorter wires. They are unnecessarily long and make it hard to stuff everything in the already small BMW cubby.

Difficult to Program

Crutchfield Customer Review (What's this?)

After hooking everything up, it took sever resets to get it to control my Pioneer radio. I think the main problem was, that the radio was turned on. It seems to automatically program only when the radio was turned off.

Works as intended

Easy and it works

Crutchfield Customer Review (What's this?)

This let me retain my warning chimes in my bimmer and they actually sound better as they come from a new small speaker, not through the stereo speakers as before. I wired it up to my radio on my desk with the steering wheel control adapter and then wired into the vehicle. It was super easy and it all works great.

Overview: The AXXESS BMRC-01 interface is designed to allow you to replace the OEM radio with an aftermarket head unit in non-amplified BMW/Mini vehicles or BMW/Mini vehicles that have the OEM amplifier bypassed. The BMRC-01 will retain all warning chimes (via built-in speaker) which are lost when the OEM radio is removed. It also provides a 10A/12V switched accessory wire for proper radio operation, and the R.A.P. (Retained Accessory Power) feature will be retained. In addition, the BMRC-01 provides navigation outputs (VSS, Parking Brake, and Reverse) to help ease the installation process.

Compatibility: The Axxess BMRC-01 is compatible with the following 2006-up BMW & Mini vehicles (as of 4/24/2015).

BMW 1-Series 2008-up
3-Series 2006-up
