Looks and works amazing

The best Bluetooth receiver I have ever used. Very easy to install and it looks great. I have used this on three different boats so far with excellent results. This time around, I decided to install it in place of my speedometer gauge on my boat because I don't need to know how fast I'm going when it's 30 mph max ha ha. Very well built. I would 100% buy this again and again.

No more silence

A few momths ago, lightning ruined the system on our boat. We could not stand the silence anymore and purchased another system! Thankfully, we found the same exact system, so no new modifications were needed.
