Instead of having 10 mb - 32 mb PCMCIA cards set up for the 'other' vehicles you are working on, or using the erase and set up function for your existing card; which can take close to an hour - this can be done in minutes.

I bought a Honk Kong China tech 2 I see even with the CAN box plugged in between tech 2 still only had programmed into it up to 2014
your saying if I use a windows 7 laptop I can down load the GPs2 . Then in have to use the laptop to plug in to a car with the tech 2
and the can box ? I'm new to this this is my first scanner I've made it this long with out ever owning or using one.
