Electronics 40-VW10 Factory Antenna to Aftermarket Radio Adapter for Select 1988-Up Audi/BMW/Mercedes/Smart Vehicles, Accessory

Installed an aftermarket head unit in a 2003 Mercedes-Benz ML500 (W163) and this adapter worked well. It picks up local radio stations even though I never listen to radio broadcasts. Pros: fit my vehicle, affordable, worked with integrated rear window antenna Cons: none It's a cheap adapter that works!

This worked on my 2007 Cadillac CTS. Good fit and now my aftermarket radio works as expected. Would recommend.

This review is for multiple items which was copied into each product review. I recently purchased this Boss Audio Systems BV9351B Boss Audio Double-Din, Bluetooth, DVD/CD/USB/MP3/Wma, FM/Am Receiver for my 2008 Smart Fortwo Cabrio and I love it! It is such an upgrade to the standard head unit. The reason I upgraded to this unit is because of the added Bluetooth/USB Charging ports. The unit itself I feel is a steal for the price. Some of the better aspects are the responsive touch screen, ease of use, and all the listening functions. If I were to be picky I would change two things. One, I would like the volume button to be more responsive on first turn. I believe that is purposely lagged in case you accidentally bump the dial. Two, the USB port can't stream from USB to iPod/iPhone. You have to either use the Bluetooth or Aux port. This was my first unit install and it was easier than expected. All the cords were labeled and I bought a great harness which made it even easier. The harness I bought was a Metra 70-1783 Radio Wiring Harness for Smart Car . It was color coordinated and made for a very easy install. It added a level of confidence for a first time installer like me. For the antenna I used the Metra Electronics 40-VW10 Factory Antenna to Aftermarket Radio Adapter for Select 1988-Up Audi/BMW/Mercedes/SMART Vehicles . It was an easy plug and play adapter. Lastly, the dash kit I used to add that OEM look was the Scosche ST2430B 2008 Smart ForTwo Passion/Pure Double DIN or DIN With Pocket . The kit came with an extra din to hold items however I purchased a double din system. The kit came with easy instructions and added a factory look. Just be careful with the provided screws because they can damage the brackets if you aren't careful. Overall, my first install was easier, quicker, and better than I expected. If you use the products in the review you wont be disappointed!

Great adapter for a Mercedes ML320 (W163) vehicle. Mercedes antenna connectors are NOT compatible with most head units and you'll need an adapter to connect them. Holds tight. Easy to use. Fits perfectly.

Works well used on my 1995 BMW e36. I added a aftermarket Alpine radio. I had room for the extra wire length if you don't you may consider shorter adapter.

I bought the Pioneer DMH-W4660NEX that has HD Radio. The HD Radio would not play because there was no antenna connected. When I tried to connect the antenna from the 2008 Smart car, I could see that it was not properly connected because the pioneer radio had a deep well (about 2 inches) for the antenna and the 2008 Smart Car's connection was about one-half of an inch. I used this antenna adapter to go between the Pioneer DMH-W4660NEX and the 2008 Smart Car antenna and it worked great.

This is just an echo of Gerardo's review. I used it on a '97 328 BMW as well. It snapped securely to the BMW connector and plugged into the back of our new JVC head unit. Other reviews say that BMWs with antenna amplifiers and rear window antennas don't work well with aftermarket head units, but it seems to work fine, even on FM. I also used the Metra harness adapter for BMW. Plug-and-play. Everything worked perfectly. I should also note that the post office lost my order. When it had not arrived after three weeks, I called Amazon and they IMMEDIATELY shipped me another at no cost to me. I love Amazon.

Although the product does not list 2002 Ford Focus for compatibility, it does indeed work on this model. Simple and clean install. The only thing I might add to improve this product is some heat shrink tubing for the female side, but that is easy to install.
