I'd like to have access to the comprehensive functions of VCDS for both my Audi B5S4 and VW Golf R32 as well as my son's VW Jetta Sportwagen. Armed only with an iPad Pro and an iPhoneX, if I understand my choices, I could purchase the HEX V2 and a PC laptop or the HEX NET together with my iPad Pro. Being new to a complete understanding of the abbreviated functional categories in the comparison table at Ross-Tech, I'm not sure what critical functions I'd be without if I used the iPad Pro and VCDS-Mobile. Please advise me. Thank you.
