I have a planet bike speedometer and after the winter season it seems that it is no longer functioning. It will come on when the bike starts to move but I cannot reset it and it seems to be frozen on the stats of my last ride where it was working. Does anyone know if this is a battery issue or just a malfunction of the device. If I have to get a new one how expensive and time consuming would it be to replace?

Have you looked for a reset pinhole or tried taking out the battery for a while and putting a new one in? –  Batman May 19 '14 at 14:00
There is a saying in computerdom: RTFM -- Read The Fine Manual. First off make sure you remember HOW to reset it. I have to retrain each spring since none of the new units are nearly as intuitive as the old Cateye Micro. –  Daniel R Hicks May 19 '14 at 15:22
Note that your problem may be that the buttons have developed poor contact. Simply repeatedly pressing the buttons a few dozen times may fix this. –  Daniel R Hicks May 19 '14 at 15:23
Put a new battery in it. That will reset the computer and fix any power related issues. –  Gary E May 19 '14 at 16:40
