Got wired, want bluetooth

I have just taken delivery of a bundle pack (ipaq 5550 and tomtom).
I didn't realise that the tomtom would be wired (I guess I presumed that if if it was bundled with a bluetooth pda then it would be bluetooth.

Is there an "upgrade" type kit, or accessory that I can buy to make my new tomtom bluetoothed (blueteeth?!)

There is no upgrade kit as such but the solution would be to buy a Bluetooth GPS receiver seperately.
