after dealing with audio cutting in and out for over a year, this simple quick installation brought my audio back. dont hesitate to try it before you start replacing modules

Exactly what I needed for my 7 series! I bought two just to have an extra one around, turned out 2 of the3 modules were bad so I needed both. I have my radio and chimes back!

1. I was able to use this to diagnose a problem fault in the radio system on a 2007 BMW 335i. Using this I was able to isolate the failed component (XM Radio module). 2. This is now used as a permanent bypass as I have no current intention to replace the XM module.

I have a 2007 BMW 650i convertible. We had taken it in in 2021 for a battery drain at a local shop. They were not much help. Not sure when the sos light started. But since then we have but it on a trickle charger every time we park it. As we don’t drive it a lot has 97,000 miles.Lately the SOS light, high drain and Radio Mode were starting to really bother me. After researching I found this product. I bought here because of what I read about customer support. I tried it on my own and failed. Adam responded to me through text sending photos and instructions to test 3 units not just the SAT that I tried. He also sent a video on the third bid as it was under my rear headrest and they were tricky to get out. As it turned out the Bluetooth was the problem. I actually preferred to replace it. Sent Adam a photo of the label which he matched to a used on on EBay about $30 total. Came two day later, installed and I now have my Bluetooth paired with my iPhone and no warnings on my screen.I am saving this part in my spare tire too area. May need up still needing it one day and Adam’s help was priceless! I don’t write to many reviews but this was way above great customer service.
