Does anyone have a problem with the Garmin 400t not being accurate? My Garmin is off about 50 meters and need to know if there is anything i can do to fix this.

Can you give more details? To what are you comparing it?
Recreational GPS units 1) typically have an accuracy of 20-30 feet and 2) typically can't be (and don't need to be) calibrated.
Are you seeing this with an address search? -- Addresses can be off in the database for any number of reasons.
Are you seeing this when entering coordinates? -- Be sure that you are using the correct coordinate FORMAT and be sure that the GPS unit is set to the same MAP DATUM as the source of the coordinates.

Yes I have the right Datum. The Grid that i get on my GPS I plot it on a map and its not right. It's off every time. When I use another garmin the grid is accurate i don't know what to do. So frustrating...

Your description says, "The Grid that I get on my GPS I plot it." I'm lost as to exactly what that means. Do you mean that you are using the GPS in an off-road environment? If so, does the unit offer a setting for off-road? If you use an on-road navigation setting to determine the coordinates of off road locations, you can get erroneous info because it is trying to snap-to the nearest road.
Nuvi 660 -- and not upgrading it or maps until Garmin fixes long-standing bugs/problems, and get maps to where they are much more current, AND corrected on a more timely basis when advised of mistakes.
