Magellan - Maestro 4000 GPS Navigation System Review

My husband and I purchased the Magellan - Maestro 4000GPS Navigation System a few months ago when he started traveling with his job.  It has helped us find places that we didn't think could have existed.  It is very easy to use and with his large fingers the touch screen is a breeze.  The only problem we have had with this navigation system is that on long trips on a interstate - the voice will scare you to death after it has been idle for a while.  One problem we have had is that is sometimes takes a while to recalculate at the beginning of a trip.  If we turn it off and go where we know to go without it, it starts back at the place where we turned it off and takes a while to update, so if you leave out thinking you know where you are going before it recalculates, you could be on the wrong track and have to detour.  We really have enjoyed this product and would still be lost if we hadn't had it on some of our trips.
