I bought my car used and the touchscreen functionality didn't work, so I've never been able to use tweaks since the control knob wasn't able to select the appropriate commands. I am planning on replacing the screen and want to install AA myself, but read here that I needed serial access when updating to v70, which I did not have at the time of the update. Am I misunderstanding the instructions or is there another option to gain root privileges? I have the new screen and serial converter coming in tomorrow and wanted to have everything ready beforehand, but this last thing has me stumped. I am following this guide, which was the easiest for me to follow, but couldn't find too much information on modding the car with v70 installed. I know there is the OEM retrofit kit which I would consider using, but doesn't allow touchscreen use above ~5mph. Is it possible to use AIO to unlock the touchscreen with official AA?
