Review on 🚗 Axxess GMOS-LAN-01 OnStar Interface for Non-Amplified LAN Systems by Ben Boulanger

Purchased to hook up a Jensen JV7020 to my 2012 GMC Sierra.

The SWC interface, which I purchased separately from Axxess, also does not work as advertised.

I have calls and can turn the volume up and down with SWC but otherwise
