im aware that 60*, the 704 only work on ross tech can cable. at the moment i have the normal 409 with my purhcased key. Just that the 409 dosnt have extra window to read errors from other cars. The 504 and the 512 ared discontinued for some reason. If my 2other cars work with vcd (BMW, advensis). I do not use cracked version or any other tweaked version from 3party of fleabay!
I may be consider upgrading to the new can interface on vag 704* as i be needing this future soon.
