Is it possible to get maps onto an SD card and get it running through there system . I just got the car 2016 model it has like a big shinny Ipad on the dash board but if i want sat nav I've to buy there card the price was nuts and I wasn't paying it robbing bastards. I don't want to use my tom tom id rather use the built in one. Is there anyway around it I see people selling them on ebay for about 100 quid . I was hoping to load it onto my own memory card and save a few quid its powered by Garmin Map pilot .
