Review on Infinity INV BC4 Pre Amp Bluetooth Controller by Joseph Hill

Easy installation. Easy to use. Has the ability to turn on when power is applied. The external amplifier is also switched on. Bought for my boat (2011 Sport Nautique 200). I replaced the 3.5mm jack and USB port in my handlebar bag without drilling a hole. The Clarion radio supplied with the boat has a dedicated LCD interface but no Bluetooth. I wanted to keep this functionality but add Bluetooth so it turns on automatically every time the boat is turned on. This is exactly what I need and allows me to skip songs without going into the glove box for my phone.
