I plan to visit a car dealership to buy a used car. I plan to have my new Autel MK808BT PRO with me to check for codes. If I have no wifi signal at the dealership, will I lose the Blue Tooth connectivity between my tablet and the Mini VCI, or will I be able to use the tablet if I use the cable to connect it directly to the Mini VCI while it is connected to the OBD II port?
