2.For the hardware, Benz star C3/C4/C5 is same function in diagnosing.

Difference:

1.For the functions, MB star c3 and c4 are almost the same,C4 can do all the works what C3 does and it is the replacement of Compact C3.
Just benz star c4 size is small and weight is light,much convience and the anti‐interrupting ability is better.
One more thing, as customer feedback, the advantage of c3 is can do trucks best.

2.MB starC3, C4 just can support Mercedes Benz cars manufactured after year 2000. Super MB star c5,Benz SD Connect C4 can support all current and new coming MB vehicles.

3.Benz star c3,c4,SD connect C4 update by Harddisk.That means when customer want to update,they need to send back harddisk to supplier,after finish update,then send back to them again or just buy a new HDD.For the long international distance,it may need about 2 weeks can complete one time update,so it is very trouble and inconvience.

Under this suitation,Super mb benz star c5 is release, it is can update through super mb star official web directly, which will be much convience and time saving.

In addition,Super mb star C5 work with W204, W207, W212, 405, 451, 452 and 454. Besides the software c3 and c4 own,it added three more software: SD Media, Xentry and Smart TAN Code.

SD Media: Video and PDF lessons;
