I saw a response on Garmin's Facebook page regarding a query as to whether Body Battery, Pace Pro etc would be coming to the 645/645M as it seems it is software rather than hardware capability.
Garmin's response was:
"I don't believe these are going to be added (to) the Forerunner 645 line. It doesn't have the software needed for those features......"
While I'm not sure whether the responder would have full visibility to the 645 software roadmap this is about the only response from Garmin I have come across to date which has provided an answer.
Unless Former Member or one of the Garmin team can also respond to confirm here?
If this truly is a software limitation that cannot be overcome then I'll accept it, but it is disappointing the limited information coming from Garmin.
