My Garmin Forerunner (wrist watch type GPS) which I have had about 4 years has gone wrong. I think it is the battery as will not charge from PC or mains. It has done sterling service and I have loads of data from it.
Can I repair it? Is this a common fault?
Should I replace it with another forerunner or is there something better around nowadays?
I used to use the HRM element as well but not the cadence part.
