Navman iCN510

I'm awaiting delivery of a Navman iCN 510 with full European Street Level Mapping to use on my bike and in the car.
As a newby, is there anyone with the same unit that has any comments on it before I unpack it and bugger it up or give myself an unnecessary headache.
I plan to install the Speed Camera data base which I've managed to install onto my Microsoft AutoRoute 2004. That's about my limit at the moment. But then I new nothing about PC's to start with and now I pull it apart all the time, whether it needs it or not.
Cheers, Brian.
