CF Bluetooth Card for the Explorer 600+

[MMFilus]

As the Atinav BT packaged with the 600+ cannot seem to manage more than one connection effectively, I need to add a CF card in order to bluetooth both my phone and TOPCON HIPER LITE+ for VRS use.

Seems like the reccomended Socket BL4535-634 card is hard to come by and a bit spendy when found. Can I use any old card that works with Windows CE .NET? Anyone have one that has worked for them?

Thanks in advance,

Matt
