I made some progress over the last couple of nights.
I received the replacement Crux Interface (Crux SWRBM-57C) from Crutchfield and soldered it to my Kenwood wiring harness last night. I've attached some photos including a picture of the "Quadlock" connector that attached to the wiring harness in my 05.
It seems to be working well although I have not tested all the controls. Here are a few observations - I will appreciate any extra information anyone can offer on these issues:
1. The illumination of the head unit does not appear to dim when I dim the gauge cluster. I connected an orange wire marked illumination on the Crux harness to the orange with white stripe wire on the Kenwood harness which is designated for the illumination connection. So, I think I have it connected correctly. It may be that the Kenwood unit is unable to interpret the signal from the Mercedes harness.
2. I can change the volume and radio station using the steering wheel controls. I can also change the track on a CD. The Ipod I connected to the system was not compatible with my navigation unit, so I don't know whether the steering wheel controls work with the Ipod.
3. I was able to answer and hang up my cell phone using the steering wheel controls.
4. The rear camera turned on when I put the car in reverse.
5. When the car was connected to the OEM radio, the radio station and CD track information displayed in the center message center. It does not display through the Crux interface. I suspect that task was just too complex for an aftermarket solution that is required to work with many different cars. However, if there is a way to address this, please let me know.
6. I cannot think of any way to retain the OEM 6-disk changer. However, I think the extra space in the glove compartment will compensate for any disappointment I feel on that issue.
7. When I turn the key to the first position, the system sounds good. When I turn it to position two, I do hear a high-pitched hum in the system. I hope that does not persist when the car is running.
8. With regards to the problems some folks have with radio reception, I offer the following. Although I was inside a garage, the radio reception was about as good as it is in my other cars. I'll wait until I drive it outside and have an opportunity to fully assess it. I connected a blue wire from the Kenwood unit designated as the power antenna turn on lead to a blue wire on the Crux harness. I think this turned on the antenna amplifier in the car.
Taken as a whole, I think the Crux interface exceeded my expectations and I appreciate the support the Crux technical staff and Crutchfield provided in helping me install it properly.
Tomorrow night I plan to complete the installation. My major issues are locating the GPS antenna and the blue tooth microphone.
