SSD My Pilot III internal batteries died and refused to recharge despite following Garmin's advice and leaving it off for a week with new batteries in it (there is a thread about it from a few weeks ago). The internal batteries (Li-Ion I think) are supposed to have a 10 year life. I bought mine from HM at the PFA Rally 2 years ago. I returned it to HM who have sent it to Garmin. Regardless of the warranty, I am not expecting to pay more than postage for getting this unit reparied as the internal batteries should, by Garmin's definition, last a lot longer than a couple of years.
