bluetooth gps device for my xda2i

[Melih]

i wanna buy a new bluetooth gps device for my xda IIi, but I can't decide what to buy..I'd pleased if u have any suggestions pls?
which one is most compatible? (I live in Istanbul,Turkey)
Is 16 channel ok or should I need a 32 channel device?
I heard that there's another popular gps software other than tomtom but I can't remember its name, are these devices compatible with most popular softwares or just tomtom?

Thx in advance..

I yhink that the best bluetooth PS receiver is Globalsat BT 339. It works flawlessly and is extremely sesitive to satellite signal. Another good aplication for GPS is Destinator 6.
