Review on 🛰️ VDO 340 786 GPS Speed Transmitter by Joseph Elvis

I had a heart rate sensor on the rear CV joint and it seemed to work fine, but once I hit 70mph the speedometer regularly went haywire and didn't show anything to match the speed. I couldn't fix this problem. I decided after much research into how well the GPS unit would work and where there were good mounting points, I found that the fiberglass was out of the way and I had a fiberglass hood. So I installed it under the hood, connected it directly to the speedometer and programmed the speedometer according to the instructions. It works perfectly, the speed is very accurate and the speedometer is always accurate and stable at any speed. This fixed a very annoying problem!
