Garmin Tread and/or XT Group Ride Tracker : £1,200 +

I stumbled on this by accident (and did a search but found nothing so apologies if y'already know )

£1,200
It'll track up to 20 riders and allow comms , even if no mobile signal
Open street maps . In Reach Technology
I think communicable with Garmin XT if Garmin Group Ride Tracker added £179
(Very possible that a Garmin XT will do similar if the £179 Ride Tracker is added, in which case that would be a much cheaper option, albeit without InReach. )
It looks like Group Ride satnav to another level ......
Can't tell you more, but may be of interest to some ?

It can also be used to control a Garmin Power Switch:

A bit of thread resurrection here! I was just looking at a Garmin XT, thinking of buying one, and the "Garmin Group Ride Tracker" popped up.

Now my regular riding buddies and I all have MSH2 (Sena or Interphone) and it works great! Really good "open protocol" comms (none of the Cardo rubbish )

This Garmin Group Ride Tracker could be a real "convergence" and radical option.

Worth keeping an eye on!!!???
