I have a question for you guys. oh and i have'nt sit thru here to read all 54 pages so dont get to mad that I havent lol. I bought the GPS unit and i cant get it to find a satellite what is a main issue with these? Also once i updated to a Ipad 4 couple years ago all the data comes in real slow on the Ipad. RPM for example takes about 3 -4 seconds to reach max rpm and idle from high rpm is the same?
