Review on 🚗 Enhance Your Car Audio: Metra Electronics 40-VW10 Factory Antenna to Aftermarket Radio Adapter for Audi/BMW/Mercedes/SMART Vehicles by Brian Cox

If you have a GM car with that horrible antenna cable and you need an adapter for your secondary stereo. This is the way! I have a 2001 Pontiac Bonneville and installed the radio many years ago. There was only one way. A Volkswagen adapter that didn't go well with the end of the Pontiac. You had to use tape or whatever you could find to secure it in place. This design is definitely the best! This adapter's plug, which fits into a GM factory outlet, has a cross engraved on the outside of the plug. So if you connect them. It fits snugly and doesn't need tape or anything to secure it. Essential for aftermarket stereo installations in these vehicles.
