In retrospect. best in automotive and automotive electronics

Functionally it seems great and according to most reviews a lot better than the original but it has the basics. My 2018 Canyon Denali has a very capable system. My collusion and roadside warnings are now a very quiet beep instead of the annoying loud de de deux that was before. It's hard to hear even with the music turned off, so you really need those annoying beeps. But the biggest problem is that it randomly shuts off while driving or even when starting the truck - no sound. Imagine you have…

If you have GM-MOST, you need it. The PAC kicked him out of the park. Works with Gen2 Volts.

Wonderful device, albeit very good. Most modern GM vehicles have a MyLink touch screen 'radio' that cannot be replaced with an aftermarket radio. Using a LOC is far from ideal in most situations, but with GM's EQ curve, adding aftermarket amps is frustrating. The factory system adds bass at low volumes and starts aggressively tightening it after about 1/2 pitch and also softens the punch (Q-factor). That means crappy sound and constant fiddling with the bass control, and the EQ.PAC comes to the

Works pretty well

They seem to turn off for a split second and then turn on again. Waited 10 minutes with the doors closed and locked and they never turned off. In addition, the backlighting of…

Easy installation, easy to install aftermarket components

Adding a subwoofer to the stock Bose system in my 2015 Yukon Denali was a nightmare. Unplug the factory subwoofer from my JL amp and I have muddy bass and terrible engine noise. I've tried everything to eliminate the ground loop, but to no avail. I tried this as a last resort before pulling everything out and living with factory sound. About half an hour to install, taking the dashboard apart and putting in a new RCA and remote (the amp was already there). I now have clean bass that matches the
