M920 tachograph

[Karl kostman]

Hello guys/gals I find myself in need of an all electronic Tachograph for my M920, I found one a while ago and upon further examination found that the one in my truck has 3 groups of wires that connect to the backside and the one I purchased had two wire groups that connect but the speedometer and the engine RPM were mechanical, the one I need is fully electronic there are NO mechanical input ports on it. The unit would have to be in excellent to new condition with NO rust on the face at all. If anybody has one of these that they would be willing to sell please send me a PM and lets see if we can do some business!

Thanks much
Karl
