Factory Bose 6disc stereo

[Tonyrodz]

I have a small 12v battery from a Dewalt tool I bring with me to test powering up stuff. Once I know which wire is power and which is ground, I'm off to the races.

Never thought of that. I used to use one of those mini jump battery things. It'll fit right in your pocket.

I think i have that same head unit in my 03 Yukon XL SLT. I added an iSimple Connect device, part no ISGM655 to give me bluetooth capabilities for music and handsfree calling. When I had a iPhone 6 the sound quality wasn't that great but with my new iPhone 11 the sound is much much better. I'd recommend it. Now if I could add front and rear cameras I'd bring my old truck into the 2020s. Any recommendations for me that would work with my factory Bose?
