Those dongles you mention run about $100 each. That GPS cable is a
bother, but it sure isn't $100 worth of bother. If you find a module
that doesn't require you to implement the Bluetooth stack, it's still
at least $50 for the component.
Bluetooth is so obscenely complex and expensive, you apparently need
a large development effort so you can use a cheap BT radio and
implement the stack in house, then sell a bazillion of them to recoup
the development costs.
Oh, and that bluetooth peripheral needs power sooner or later, so you
either change/charge batteries, or you plug it up.
I was excited about bluetooth until I gave a serious look at
implementing it with my APRS rig in the truck. It doesn't look so
