Nuvi 465t help

Hi my brother in law has bouught a Garmin nuvi 465t which is fantastic, but when he uses it in truck mode it sometimes freezes in the uk. Does anyone know if this is common fault? Also in truck mode it does not re-route again does anyone know if this is normal?Thanks in advance.:D

Did you make a firmware update with Garmin WebUpdater? It's well known, that Garmin devices are "bananaware", so that they have to mature at customer with many updates of unit software.

Thanks for the response. Yes we updated the firmware with the WebUpdater with all the firmware available.
