I buy this item because I want to have traffic info give the fact that I live in a busy city . happily I follow the provide route , only to get stick in a traffic jam . this thing do not provide any traffic info in South Carolina at all . for the rest it function quite well , although it do not see much use road even with the latest update . a nice example be Palmetto commerce parkway . a four lane commuter road . accord to Garmin it do not exist . update it be a pain . it take forever to download and install map . still , way better than Tomtom , which try to get I to drive into a pasture .
