Summary: Purchased the 3450LM for wife for Christmas, and after 6 months I'm ready to toss it in the trash. I purchased this because of a certain consumer reports review giving this high ratings.I've owned several Garmin's in the past and when the wife's started acting up(locating satellites for 15-20 minutes)I went for the top of the line. First off you have to read the manual just to figure out how to save an address's, only thing is there is no manual!! you have to go online.
Summary: I downloaded the Europe map to a micro SD card before we went to Ireland, Germany and Greece. We were surprised how fast the GPS located it's position when we arrived in Ireland. Another surprising feature was that our hotel was loaded in the Europe map. The GPS took us from the airport to the hotel with no problems. the next day we drove to Waterford using the GPS. There were no problems.
Summary: First time I tried to use this I followed the instructions to run software updates. Post-update, the device would not even boot up. Nothing on the Garmin support website was of any use. Waste of money.
Summary: Ok my 3450 worked for about 9 months then stopped charging. Granted I used the heck out of it during this time and was really sad when it died. I RMA'd it with fingers crossed and was thrilled to see that the return was quickly on its way. Well, it never arrived. This is where things get interesting and the reason for my review. The shipper (USPS) said it was delivered and they stood by that. I called Garmin and let them know the situation.
Summary: I really love the Garmin I work at Enterprise car rental and I use it ever day. Live in MS drive to Al and it always gets me to the right place. Love that it tell you the address on the left or right . I have a tom tom and doesn't do that.
