MB Star C4 Connect with xentry software for Mercedes benz car and trucks diagnostics and programming. One of customer have order single SD Connect C4 mux hardware without xentry diagnostics software and laptop, work with the 2017.05 Xentry Mercedes diagnostic software working well. Below share SD Connect C4 review. MB Star C4 Review on Forum: Mention Star Diagnosis sds C4 mux, it seems that there’s a lot of different manufacturers and quality levels of multiplexer clones. Here’s the one I went with, however I didn’t bother with the HDD/software they included or a dell D630 laptop. I have a background in computers, so I set myself up a vmware virtual machine and installed all the software with the (occasionally somewhat difficult to follow) information on mhhauto. I have heard of people having problems using VMware, but I didn’t experience any myself. As for the hardware itself, mine is of decent quality sd connect c4 from eobdtool.com . I have no real complaints with it other than it losing it’s WiFi configuration once drained of battery (which happens quickly, but it’s not really an issue since it draws power from OBD when connected), but I prefer using a cable connection anyway….
