I purchased this unit two weeks ago and I have tried many different ways to get this voice prompted directions correctly. But almost everytime, the voice directions are not consistent, and many times the directions are too slow. It tells me to turn after I passed a street. When I tried to follow the directions, and 50% of the time I get lost because the directions are too slow.I called the tech support and they keep telling me that the unit seems working, of course it is working. It is just too slow to use on the local streets.DO NOT BUY THIS UNIT. YOU WILL REGRET LIKE MYSELF. SPEND YOUR MONEY FOR A BETTER NAME BRAND.
