Hi I’m a driving instructor and I need to save routes for my pupil. My Tom Tom go 5200 is not saving any routes. It shows the flashing red dot when I start recording but when I stop it dosnt come up to the next step where it normally ask you to put a file name and save it. I’ve just wasted one hour route which I thought is recording but it didn’t save. My free internal storage is 3.26 gb. Any suggestions on what to do please?
