Having purchased a preloaded hard drive from Aliexpress with Xentry and a load of other Mercedes diagnostic tools, here Xentry is being used to carry our a quick test. This is the first thing the dealer tech does on your car.

The item I purchased was the Top Openport package (the webpage is confusing ... you need to select the option that includes the hard drive. My order included the 360GB HD + Tactrix clone Open Port OBD unit + remote install service).

The package came with a Tactrix clone Open port OBD unit. It was junk and failed the second time I used it. I purchased the a genuine unit from Tactrix in CA, and that has worked perfectly since.

I installed the HD in a Dell laptop. It is full loaded and boots to W10. Make sure you turn off all Windows updates! The seller uses Teamview to register the Xentry software on the laptop. I left the laptop turned on and opened a teamview session, and once I had notified the seller by email that everything was ready, within 4-6 hours they had completed the work.

The HD is preloaded with Xentry (which they setup for you), Vediamo, DTS-Monaco, EPC/WIS. EPC/WIS will work as is. Vediamo and Monaco need to be setup (or if you resourceful, you can do so).
