Review on 📡 SCOSCHE Multi-Vehicle All-Inclusive Antenna Adapter UAA3 by Grant Zeeb

It definitely works in my 2011 Sierra but I don't know if the labels on the connectors are wrong for the make of car. I forgot if it was VW or another brand but the GM connector didn't fit. Another did and works. If GM fitted as labeled I would give it five stars. The only other issue is that it's quite bulky when you're trying to fit all your radio wiring harnesses into a small space.
