I bought this for my service truck. Talk about taking the stress out of finding things. I personally don't use the voice feature at all since the radio is normally on. I picked this unit because it has a banner across the top with the name of the next street to turn on. I strongly recommend a rubber case for around the unit. I bought a tough skin for it. The suction cup works really well but occasionally it will come off (Florida Sun). I've used it on trips to find food and gas stations. It recalculates quickly when i decide to go my own way. Sometimes it takes a few minutes to pick up satellites initially, usually when I'm trying to pre-program a location at the house. I've never had it take more then a couple of minutes while in the Truck. After it finds the satellites i never have an issue. I find that the footages to next turn are a little off when it gets to the lower numbers. I've found using common sense works a little better then going buy strict footage which seems to be at the middle of the intersection or beyond. Fortunately the name of the street is in the banner. I brought this on our last trip to visit our son at in NC. Driving from the airport was a breeze since i had the address of the hotel already programed in. I love the touch screen and the way you can scroll around a map.
