Hi there! I´m planning a motorcycle trip to the Alps so i´m looking for a gps software for my iphone 5s. But the more i read, the more i get lost as each software has upsides and downsides. So, can someone please help me on this? I need a gps software for my iphone that: - Allows offline navigation (maps on the iphone and using only internal gps antena) - Allows to import tracks/routes pre-planned on my laptop - That does not re-calculate the imported tracks/routes from laptop (very important - i want it drives me exactly through the course i planned on my laptop) - Allows turn-by-turn navigation for imported tracks/routes - If i get out of the course (by some reason), it can drive me back to the original course (to the point where i got out of the course or even to the nearer point of the original course). Btw, a friend can borrows me a Garmin NUVI 2545 LM (Europe). Does this device allows the above needs? Anyone, please? Thanks!
