When bench tested the radios work like they should. Crutchfield says the issue is in the bike which I tend to believe but why does the factory radio work like it should if it's a bike problem?
Correct, in this case. The Boss Elite is a plug and play unit that does not need any special doo-dads to make it work on the bike. It uses the on board handle bar control switches without any needed hardware.
If the radio is not working then call up Boss, Not Crutchfield.

Yes, it is a plug and play radio with 4 Channel operation. No additional parts required for handle bar integration.

I looked at that radio and I was thinking I'd try it.
As it looks like it only has TWO outputs to front and NONE for rear speakers, is that what you have set up?
You have an UC so I would think you'd have the rear speaker pods........
No Sir, The Boss Elite is a 4 channel radio with a fader but you can set it up for a 2 speaker operation.

2 speaker set up



Pin designation. Plug 27A is the plug where all the radio controls terminate to

Default Problem solved! Thanks everyone.

The radio was bench tested at Crutchfield and it worked perfectly so I took your advice and got ahold of Boss directly. I got ahold of Boss tech support and they were absolutely zero help. They couldn't even get me a pinout diagram from their own radio. I did figure out the radio was locked on Aux mode causing every function on the radio except for the volume to not work. After a ton of probing and schematic chasing I found an input to the radio coming from the rear radio controls on the tour pack for push to talk. I cut that wire and everything on the radio works perfectly now. The circuit must have shorted somewhere causing it to send a signal all of the time. I don't use the rear control anyway so problem solved! It still makes no sense why the factory radio worked perfectly? Thanks for everyone's input on my problem.
