I like the gp ... as far as the map and navigation go , this be a great unit . the lane assist be also a very nice feature but the mount be terrible . it take a while to figure out the suction dial on the window mount but once you do it work ok . the suction be very tight on glass -lrb- do not work on the dash unless you use the sticky disc that come with it -rrb- but the GPS unit pop off the mount too easily . I have a Buick Enclave and it be very hard to reach the windshield to get the unit mount . they have to come up with a better way to mount this thing . I buy a additional mount that hook on the vent louver . hope this will work better ! at least I can reach it !
