just a few is enought. With HRM with small recording < 20 i get the error. But I think I'll reset my watch because many things gets easilly out of memory.

Thanks! I'll take a look at the graphing and will try and see why it needs so much memory.
Did you have a lot of HRM and/or GPS recordings? Or it failed even with just a few in there?
