My 1040 solar for cycling has stopped showing percent elevation, continually re-calculates, keeps re-routing, the map spins a lot and the speed & distance shows zero at times. My device is a little over a year. No matter where I ride, these problems occur, & more frequently lately. I'm very disappointed & frustrated with this expensive device. I've been offered a refurbished device by the company. But that don't sound good neither. Is it time to just give up on this faulty product? :( HELP!?!
