Many people on the internet all said the MB Star Diagnostic Tool MB Star C3, C4 software is the same, C4 whit SD CONNECT also with this software, and for the hardware, C3,C4 is same function in diagnosing.For mercedes Benz, C3 and C4 also can do work, in my opnion, C4 work with all the benz and more than C3, but C3 can do benz truck very well, this is advantage for c3.C4 is much stronger in anti-interrupting ability, when C4 tests cars, it’s hard to influence by the environmenr outside, such as magnetic field，noise. C4 is much smaller in the appearance than C3.Benz compact 4 SD-Connect is a latest Benz wireless multiplexer. It will connect to the PC by wireless connection.The biggest difference, i think, is connection wiring mode, C3 need 232 port, but C4 can be used with network port, even wireless.Also, the price C3 and C4 is very different, now C3 is the half price fo C4 as far as I know. could you some guys add more infos? i want to know more, thanks.
