I am looking for knowledge - What are people using to read codes, troubleshoot, light prog etc. from the 2014+ models
What I have read is that the Tech2 (clones and vxdiag va nano etc) only go up to 2013 models and I know the Internet wouldn't lie to me
Educate me please
Haha, you gave me a good laugh with Internet lying.. Thank you.. Some of the clones may not go past 2013 as they may concentrate on the vast amount of vehicles that are still around. The vcx nano that you mention does both albeit in two different ways. It does come with two different programs one of which is called Tech2win which is an emulator that is the same as a physical tech2 but you need a Laptop or tablet for that. The second program is the GDS2 which you do need for GM vehicles after 2013 although some earlier ones do use it as well, Equinox and Terrain are two at the top of my head.
Neither program is dependant on the other, but they both need the MDI clone or Nano. The nano plugs in to the obd2 port and then either hooks up with a usb or wifi depending on the version.
Both of the programs do work and they will save a lot of money. BUT.. they can be tricky to install and operate. The reviews for this unit, are all over the place so buyer beware if you are not comfortable about chinese knockoffs.
