🔌 Enhance Your Non-Amplified System with Axxess GMOS-LAN-03 LAN OnStar Interface Review

I was upgrading my stereo and needed to keep my On-Star, phone and turn signals working. Unfortunately you have to buy the relay, extra speaker and push button switch separately if you want to control the volume. For this money they should all be there as the part is a small box with cables and connectors. The instructions were clear and easy to understand and now everything works perfectly.

I bought this hoping this model number would fit a 2011 HHR. It was said to run through the 2009 model year. I work and my OnStar works great. I had to call tech support with a question about a plug that wasn't being used as the instructions were very vague. They were complete idiots and I almost started yelling at the technician. But everything is fine. A great option to order if you have a radio with navigation.

Works well. Installed Pioneer AHV-X3800bhs. The instructions are general and you had to rely on the attached schematic to understand everything.

But the 'Security' indicator on the dash now never lights up, and when you open the door, the alarm no longer sounds. 3 months after…

This unit was the only option and a must to hook up a new radio to my '08 HHR. Unfortunately not well thought out and not fully functional. Pros: * It supports On-Star. * It allows the radio to interact with the factory seat belts. * It supports ringing when the doors open/light up/put the keys in the ignition. Bad: * DOES NOT SUPPORT turn signal "click" signal without EXTRA resistor that needs to be purchased separately! Forgive me but I expect EVERYTHING to work for the price of this item! *…
