Summary: I have just moved to a new city and the Garmin has helped me locate all the places I needed to go to get things done, eg. bank, stores, courthouse, doctors etc. I don't think I could have found all these places without it. It is so simple and easy to use...I never leave the house without it.
Summary: Seems more difficult to just enter an address and go. Attempted to find an address that I knew was correct and kept getting the message that there was no info for that address. Entered same info on Bing Maps and directions showed immediately. Graphics more difficult to see than on my 3.5" screen. I like the split screen for highway exits. I'll attempt to get used to this GPS but not sure I,all like it as much as the Nuni 255.
Summary: I bought this unit to replace 5 year old Garmin and to get updated maps. I like the larger screen, volume is loud,three different views of intersection,recalculates silently, intuitive search function,just type in address and will search the whole country. Voice command is challenging, but go "home" works well!
