Advent OGM-1 Navigation for sale
I purchased and installed this unit about 1 month ago in my 2011 Avalanche. Very complete, and very easy to install. Comes with everything you need, harness, mic, GPS antenna, etc. It looks factory and it integrates with the steering wheel controls, bluetooth, backup camera, etc. If you do some research, it is pretty clear this is the one to have. Check out this website for a TON of info on it: www.adcmobile.com and also check out the comparison chart there.
I am selling it for one reason: it does NOT integrate with OnStars driving directions, and my wife says that is a must-have. So my loss is your gain. This thing is practically brand new. Asking $850 shipped within the lower 48, PayPal only. I know I am a newb on this website, so if there are any other questions feel free to shoot me a PM. Thanks!
I will be posting pictures of it tonight......
