My Garmin nuvi 2250 is about 2 years old and is very slow on selecting cityies or streets while I'm searching adress. When I enter city name and select the citiy i need to wait about 10 seconds to open street search form and after entering street the same problem again. I cleared all searching history and trip log but the problem is still here. Any help please!?

If you have more than one map on your device, deactivate or better remove old and not used maps.
