Didn't have to wait long... It's fixed!! Bluetooth is now available to PDM via a little piece of software called SerialClent, available here ==> http://eudyptes.com/SerialClient.php A little kludgy but works and now I'm happily playing with my bluetooth GPS receiver, using Street Atlas and Streets & Trips both in Windows XP on my MacBook running PDM. Fantastic. Never would have dreamed just 1 yr ago of such a thing. Well done.
