Here is your answer: BLUE TOOTH = NO WIRES!

That is wicked, I wonder if there are any of those little gadgets avaliable in the USA.

If so, that serial - blue tooth thing could be used as a modem cable too?

Found a few links:

Bluetooth Serial Adapter:
http://www.socketcom.com/product/CS0400-479.asp price is $160

Samething but cheaper:
http://www.securemart.com/cgi-bin/fu...6.html?pcode=4

Does any one know, if its possible to use the following
PC > USB Blue Tooth \/ wireless link thru bluetooth \/ USB Blue Tooth > USB > Serial Adapter > GPS

Why not just get THIS and a USB BT Dongle. That is what I did. It has a 8 hour battery life as well.

Thats what im wondering. By the looks of things you can get a USB bluetooth adapter and a Aircable serial module for $49 and pair the dongle with the module and have a wireless serial > bt > USB link.
I think this would be quite good if it works with any BT dongle, because the total wireless link would be $49 for serial adapter and $30 for a USB BT dongle.

I have e-mailed them asking them if it will work with any bt dongle. fingers crossed hopefully it will.

I've checked that page
IT IS NOT A pure BLUETOOH SERIAL
it will be searched as another BT device but can works fine as a serial
