Hum when using this interface

My original stereo through Bose speakers had decent sound, but limited to FM as the cassette was broken I removed the radio and replaced with a Pioneer with a CD. When using the Bose interface I heard a hum at all volume levels. I connected the Pioneer directly to non Bose speakers and it sounded perfect. I expect some internal issue or shielding with the Scosche interface so I will not be using this product other then for the GM connector and non speaker wiring.

Easy Install-Problem with Directions

This product was easy to install and works well. However, the instructions are not clear on how to connect the wires that power the speaker amps. Fortunately another review solved the issue for me.

This harness wired in so quickly I thought I was doing something wrong. Highly recommend. Plugged it in to the old Bose harness and that was that.

Installed in a 1987 Camaro

I used this product to install a Retrosound Newport 1.5 DIN in a Bose equipped '87 Camaro. The product did everything they said it would. I'm very pleased with the results. The install is very straight forward but there is an issue so I'll try to explain. When you remove your GM factory radio there is a pink wire connected to the radio separate from the wiring harness from the vehicle. Directions do not sufficiently address this. Tech support at Crutchfield was very helpful! This wire is a key element when wiring your aftermarket radio. It is used to turn on the Bose amp. The pink wire is to be attached to the SOLID BLUE lead from the Scosche wiring interface AND the BLUE/WHITE lead from your new radio wiring harness. You will not use the solid blue wire attached to the new radio harness. To facilitate the connection, I cut the pink wire (with plug) from my factory radio. When I connected all of my plugs during final installation, this made a simpler hook-up. This connection operates the amp AND the power antenna.

Needs more installation info

The color coding of each wire makes this very easy to install. However the guide was inaccurate when it said that the pink wire was not used. Turns out after reading online that the pink wire is the on/off wire for the Bose amplifier to each speaker. Had I not found this out online, I would not have been able to complete the install. Also the adjustment buttons for the gain are rather weak and could be stronger. Other than that...the instructions were good and the color coding makes it virtually impossible to mess up.

Great product

Overall was a great install. All wires were perfectly color coded. This went in a 1985 Corvette. Only had an issue with one wire. There is a pink wire on the factory harness and no lead from This harness. I had to cut the original from the radio and install it directly to my radios amp wire. Basically building a simple harness for the factory amp. I called support here when I wasn't sure where the wire went and they knew exactly what I needed to do. I did break one of the pots when turning it down, but got another one and a few minutes soldering the new pot and all was well. Total install time was around 15 minutes without the solder job included. Be careful when turning down the pots they break off easily. 4 stars since it didn't have the amp lead built in. otherwise perfect product.

Scosche CGM01 Wiring Interface

I am not good at auto wiring so when i opened the adapter i was a little intimidated with all the wires i used the supplied crimps to connect the color coded wires. I had two problems i thought one of the ground wires would have to go to ground on the car but i called and you only have to connect the two ground wires together. I had one wire remaining a blue wire it had to connect to the cars amplifier. It took two phones calls and the help at Crutchfield was great ..They knew there product very well... I would buy from them again in a heartbeat!!!!

Not enough connections - wires left over

I don't know exactly if or how well the part works yet as I am still trying to figure out how to install it. I know how all the "existing" wires of this harness connect, but I still have three wires "left over" from the original installation. The wires that are left over are somehow related to my existing speakers and pre-amps, as when I disconnected them from my original radio, the speakers quite working. Unfortunately, the installation instructions received from Crutchfield do not address these "extra" wires in any way...the instructions are minimal and not specific to my particular car/system. I'm going try to contact Crutchfield's support line this weekend to see if they can shed some light on this. On the positive side, I'm sure learning alot about how stereo systems are installed since the instructions are so minimal and general, I've had to get out my volt meter and experiment with the wiring to understand what is what. Crutchfield's website gives you the impression that installing a stereo is easy, but I'm not finding that to be the case. It is interesting though!!
