PC7 only work with SRM

You'll need 510/810 or 1000 garmins.

Older garmins don't have disable-auto zero in the firmware, so you're forced to buy new garmin!

Yeah looks like it doesn't it. Booger.

They removed disable auto-zero in a firmware 'update'.

As before though I suspect I can bodge it to work by removing the head unit's ability to detect speed.

skinny in reply to @Howard

Yeah. Force you to buy new one.

I don't think you can roll back the firmware either.

If you borrow a Joule headunit you can disable autozero in the hub (and it's stored in the hub)
