Cheap truck nav

Copilot truck is around 9 quid a month. I have enough crap to lug around with me as it is and I don’t want to have a sat nav onto that list. I always carry my phone, so it makes sense. I always switch to google maps to walk me to the door. Much more accurate and I’ve only been put wrong 2 or 3 times since I’ve been using it, and then not by much.
