Bike and PDA

Wanted advice on a pda, gps reciever and bluetooth combo suitable for mounting to a motorcycle, has anyone had any experience of this type of use?
Would like suggestions on mounting points of pda and reciever if possible.

Also which pda and reciever combo works best ,i'll also use it for the car as well

Thanks in advance
