Add usb to radio

[dirtdriver11]

Anybody found a way to add a usb port to a 2008 sierra without changing radio?  I have the 6 disc/am/fm/xm radio now with bise option.

it could be done if you added usb hardware and firmware to your radio. then you would need memory for your buffer and a pic controller piggyback to keep the bus and memory addresses in order. next a digital to analog converter followed by a pre amp stage to feed your radio.  not worth the effort, but hey...it can be done

Sounds like it would be easier to find a factory radio that already has it!

I have one out of a 13 that has the USB I would sell for 75 and the shipping cost
