Why should buy MB Star Diagnostic Tools Xentry connect?

After 2015, all Star Diagnosis equipment is no longer supported. That means there is no update diagnostic data for the newest cars and their systems. The lack of the possibility of coding and programming of electronic units due to the backlog of the software data level in the device, from data in the electronic control units of the car.

At the end of 2014, among dealerships, almost all of them who previously used Star Diagnosis Compact4 with SDConnect DoIP multiplexers were almost gone. Instead, dealerships choosed Xentry Kit kits which include the latest Xentry Connect multiplexers and Xentry Tab tablets from Panasonic. Tablets are custom-made, also they have a “civilian” version – the Panasonic Toughbook CF-D1, which has a more powerful configuration but shorter battery life than the original Xentry Tab.

Honestly, it seems exaggerated for non-dealer use Xentry Tab. While for dealers, that is necessary.

And what about workshop service?

Undoubtedly, the tablet from Panasonic is well while the price is too high. The cost of the Japanese tablet is realistic to buy pieces of eight new laptops or tablets from other manufacturers.

So , we suggest to buy Xentry connect from us , then buy a laptop yourself . the software from which Xentry Connect is managed can be installed without any problems on any computer that has a 32-bit version of Windows 7, Windows 8 or Windows 10. It’s clear with Xentry Connect itself – there’s no alternative .

After all, in this choice there are many reasons that encourage one to make a decision. The main thing is one: since 2015, the diagnostic multiplexer Xentry Connect C5 becomes the only one used at dealerships.

Thus, by purchasing this equipment, you do not lag behind the progress. You use in your work the best that is available today. Each your client, seeing with his own eyes that you in your work use the same device that he saw at the dealer’s service station, will understand that he made the right decision entrusting his car to your specialists.

Real MB star C5 price:

As for the price, real MB Star C5 will be sale 1095 EURO in eobdtool.co.uk without shipping cost. The price is about 2 times higher than the old C5.
