Big screen navs sound like a good idea but I have found that except for rare cases of "not sure which way she means" the voice prompts are all you need. So 99% of the time I get by with voice prompts alone no screen even needed. Glad to see Smart is using what looks like the Garmin 5 series like I have, awesome unit. One of those can't live without it type deals. And that silver ring around the screen comes off, they have lots of color options available that just snap on, like the Smart skins. Xcellent choice Smartcentral.
