:2thumbs: There are some good features & farkles to help you enjoy the most out of it.
It took some investigating to learn my 660 & know I still have more to go, but have found the features that help me most for now. #1 fuel tracker. Set a predetermined mileage & warning range, when you get there a red fuel pump will show on screen, touch it & it will provide a list of various stations & how far off they are:thumbup: pick one & it will show you the way. (Sometimes the information is wrong station closed or burnt down:dontknow: just pick another on the list)#2 doing poker runs or the passport at Spyderfest you can pre program a custom route of all the addresses & it will give you options on how to complete , fastest time or shortest route, you can arrange & edit the order of locations, takes lot of slow typing but does work.#3
been looking at getting the kradlelock for security

the unit does offer a 4 digit pin code, if fails the unit will not unlock unless it is at preset unlock location. :firstplace: #4 Adding a memory card allows me to back up & add files easily from pictures, locations, & MP3's. Actually had a update almost lost my saved data

thankfully that recovered & is saved in several spots now

. Good luck & enjoy
