Possible to use VXDIAG VCX NANO with Mercedes?

Question:
I have a Chinese VXDIAG VCX Nano for GDS2 works on GM, when I try it on MB passthru (2019.03) I get a error
" Error License For Function: BENZ "
can this be fixed?
can I buy a license?

Solution:
The vcx nano for GM has the j2534 protocol only for GM cars. If you will try to use it with another j2534 compatible app like xentry it will not work.
vcx nano is a single car software passthru. It does not compatible with Mercedes/BMW/Porsche software even you buy a license.
For MB passthru, you need a vcx plus or benz c6 doip interface with a MB license.


FYI:
But still some people make it work. You are at your risk.
You can use VCX Nano and Xentry passthru to do almost 98% of all diagnostics.
It also connects through Monaco (smr-d files) and Vediamo (cbf files).
To achieve this, you need,
1) to use VX Manager 1.3 and not 1.6
2)While installing drivers, ensure to install Toyota (if the nano is for TIS version) and passthru only. Do not install/tick Benz software.
That way, you will be able to use it. I have used this tool for the past four years and rarely disappoints.
