Try and find the older gps puck and drop back the firmware and cross your fingers and wait for a firmware update. I found a place on Amazon or E-bay don't remember which with the older puck but the guy was off his rocker asking $250 or so for them ouch! I went ahead and bought the newest gps puck I,m making a portable unit and was going to stick the new puck on my boat. But I,ve sense changed my mind and I,m going to put the new puck on the portable Unit because I'll just be using the GPS\Lakemaster chip anyway. There';s sonar on Dad,s boat already. But now I'll have to switch back and forth between the older up date and the newest one when the 858 comes back to the bow WTH! Heck is that HD unit even backward compatible with the older puck?All the BestGat
HB pushed out the newest update yesterday. Give it a go and let us know how it works.
