just got a new gadget for my birthday.... from woolworths... RAC sat nav system... by route 66 4" screen... (sat nav 110- navteq)...

has any one else got one of these ?
how do you rate them... i cant really find much info on them on the net and i wanted to clear a few issues up...
firstly, the fixed speed camera alert option... i cant find any option to turn it on/off or choose the type of alert or distance etc.. nothing on it at all really?
secondly, if i search for a house number and a postcode, my searches arnt very sucsessfull? think im doing somthing wrong?

any comments are greatly recieved with thanks.
