GPS Data Logger Software - BT747

I have here a NavGear (www.navgear.de) PX-3015 from Pearl (www.pearl.de). Inside is a sticker (over another sticker) with "Model: DL-3200BT Ro" and "Item-No: PX-3015". Btw: PX-3015 (or PX3015 is a pearl name (NavGear is a company owned by Pearl), but the name "DL-3200BT" does not appear in any Pearl documents. It seems that the device is made by and a product of ebontek (I assume that they could be "real manufacturers" of them and the others are "only branders"). As it was a "last piece for special price", there was no software included, so I had to find one that is working – and BT747 is working! So please add it to the list with the supported and compatible devices.
