Garmin 64 Series Firmware ver 4.70

Recommended Posts

Just a note to let folks know that Garmin has published a firmware update to the 64 series GPSr units. That usually means others too, so you may want to fire up Garmin Express, Basecamp, or whatever you use for updating your handheld units.

The 4.7 update appears to have some functionality or fixes related to external sensors used on bicycles such as cadence and wheel speed sensors. There was a fix related to tracking too.  Anyway, here is the summarized history of updates and what they fixed or functionality they added:

I'm unaware of issues with that HC. Please do tell.

Does Garmin know about it? I can bump caches to 62s from my 64st, but I haven't tried to share caches to anything else.

It'll work once, then one of both parties have to reboot their units to get it to work again... especially on 64 to 64 transfers.  Kirbydox, Lola and I struggle this this all the time.  It seems to work a little better transferring to and from the Montana, but occasionally that locks up too.  It's been this way since day one.  Other times, it will show to transfer a cache, but the cache never appears on the receiving unit.  It has a success rate of about 20%.

The wireless transfer always worked better on my Oregon 450 than the 64s and predecessors.  Now that I have "upgraded" (?) to the Oregon 650 that functionality has gone to less functional than the 64s.
