Good item

It worked good in my 07 chevy 2500hd. Easy plug and play with all factory options!

So far, So good.

Easy to install. Like the fact the SWC is built in on this model. Would recommend Axxess products to any DIY installer. Instructions are easy to follow. Fits easily in the space in my car.

Great harness

I'm loving this harness so far. Didn't need extra hardware or harnesses for the steering wheel controls,was built in. Works fine with the stereo I bought with it. Would recommend.

wiring harness

I bought this to go into my 2012 suburban LT I returned this not because is wasn't what I was looking for but because I decided to use the Maesrto RR so that way I could get a few features that weren't on this harness. there are a lot of good things that came with this product that I could find anywhere else like the USB retain kit but that's ok I found other ways to deal with that. I would recommend this product to someone looking for a easier install then the Maestro RR

Awesome!!!

I bought a Scosche aftermarket adapter and it would not work in my 2013 Silverado, I talked with Sonic Electronix and bought the GNLAN29-SWC and boy it was just wire stereo to adapter wires and Yes! my stereo came on and in minutes had steering wheel controls too. Love them, definitely will be a return customer.
