Review: Worked Perfectly For 1998 Mercedes E320 W210 Wagon - I upgraded the single din radio head unit in my W210 Mercedes wagon with a Sony model, and when I bought the wiring harness, someone recommended I pick this up to as the antenna would not plug into my new radio otherwise. This did the trick, was inexpensive and installed easily when I was switching the head unit over, works perfectly! Even though I do not listen to the radio all that much, I would have regretted putting it all back together without the antenna hooked up. No wires needed to be cut, on any of it. Awesome. Review: Excellent Product - Most online forums state it is not possible to upgrade or install an aftermarket stereo into my automobile due the factory Bose system containing fiber optic cables. After extensive research and connector mapping, I determined it is entirely possible, but I needed an antenna adapter to finish the stereo upgrade for my 2003 Mercedes CLK430. The vehicle's antenna connector fits very tight onto the adapter, which is something I really like. It essentially eliminates the possibility of the cable popping off during the final radio installation. It works great and I'd recommend this for anyone installing an aftermarket stereo into an applicable European car. ## Features - Easy to use - Easy installation - Fits into factory plug - Great for all your needs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007WQ8XY | | AntennaDescription | Radio | | Best Sellers Rank | #419 in Car Audio & Video Antennas | | Brand | Metra | | Built-In Media | Volkswagen Aftermarket Antenna | | Color | BLACK | | Customer Reviews | 4.6 4.6 out of 5 stars (645) | | Global Trade Identification Number | 00086429010240 | | Impedance | 50 Ohms | | Item Type Name | 44-Ul15 Locking Top Mount With Key For Universal Applications | | Item Weight | 4.54 g | | Manufacturer | Metra Electronics Corp | | Number of Channels | 1 | | UPC | 617407388619 755034093053 012304442837 052778841460 086429010240 163121225216 012306021924 | | Unit Count | 1.0 Count | | Warranty Description | Please contact the manufacturer | ## Product Details - **Antenna:** Radio - **Brand:** Metra - **Color:** BLACK - **Global Trade Identification Number:** 00086429010240 - **Impedance:** 50 Ohms - **Manufacturer:** Metra Electronics Corp - **Number of Channels:** 1 - **Number of Items:** 1 - **UPC:** 617407388619 755034093053 012304442837 052778841460 086429010240 163121225216 012306021924 ## Images ![Metra Electronics 40-VW12 Factory Antenna Adapter to Aftermarket Radio Adapter for Select 1988-2005 Audi/BMW/Mercedes/VW Vehicles (VWAB) - Image 1](https://m.media-amazon.com/images/I/51ZojuMborL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked Perfectly For 1998 Mercedes E320 W210 Wagon *by J***E on October 12, 2023* I upgraded the single din radio head unit in my W210 Mercedes wagon with a Sony model, and when I bought the wiring harness, someone recommended I pick this up to as the antenna would not plug into my new radio otherwise.
