You have to input your address search twice to get this unit to make it work; there have been a few times it will not find the address that you may be looking for in its database.If you try to run both the navigation software and all the other database software it seems to slow down its processing speed.If you ever lose battery power completely you will have to reload the navigation software all over again! I do NOT particularly recommend this unit (even though I own one!)
