Pairing GPS /w BT to truck stereo /w BT

[Rune75]

I have a 07 Dakota Laramie that has a BlueTooth enabled stereo. I currently use the BT to pair my phone & stereo. Now I see a bunch of BT enabled GPS on the market but it seems they only sync to phones.

Will any BT enabled GPS pair with a stereo so I can get that tinny sounding voice onto my speakers (without using an audio cable to my AUX port on the back of the deck)?

Any info will be greatly appreciated!
