Garmin GPSMAP 67i software v8.80 problems

Ok so I bought a GPSMAP 67i and since the new software update to V8.80 it is constantly crashing when I try and load a route that has been made on the explore website or app. Has anybody else had this ?

Garmin have since sent me a new device out and I was advised to let it do the update but it is still doing the same thing. Even after a hard and factory reset and clearing my accounts it is still crashing out and rebooting when I try and load a route.
