I am using a Dakota 20 with a original Garmin Heart-rate-belt to record my heart-rate on my mountainbike tours. I found a bug in the Dakota Firmware:
The heart-rate is recorded fine as long as i ALWAYS stay in proximity of the Dakota. When i leave the receiving-range of the Dakota, my heart-rate is no longer shown on the Dakota. If i re-enter the receiving-range the heart-rate is shown again. So far, so good.
BUT: from the point of leaving the receiving-range of the Dakota, even if i re-enter the receiving-range shortly after, the heart-rate is no longer recorded in the GPX File. I could test this behavior on several occasions.
Even short toilet-stops break the recording of my heart-rate :-(
Which is the best way to report this bug? Is there a special email address for reporting firmware bugs?
