Danctnix USB GPS for Pinetab2

[biketool]

I have a NEMA GPS dongle 

Code:

Bus 003 Device 004: ID 1163:0200 DeLorme Publishing, Inc. Earthmate GPS (LT-20, LT-40)

Danctnixfor the Pinephone and PPpro I assume have working GPS and mapping that attach to the USB device generated by the modem package. 
If that is the case what packages sould I Syu or flatpak onto a Pinetab2 to get this setup so I can have bigger screen navigation with the GPS receiver suction cupped to the window vs inside the device?
(edit)
It seems like there is a problem with the cypress_m8 driver since around it's introduction in 2005 so it requires a kernel patch to receive the NEMA feed see 1 & 3.

2 - https://github.com/torvalds/linux/blob/m...press_m8.c
3 - https://bugs.launchpad.net/bugs/111694

3 uses a fix referred to in 1 though this seems to be sub-optimal commenting out this line and recompiling 

Code:

cypress_set_dead(port);

I had found these Delorne Earthmate dongles on the auction site for $5 each.
(it makes me wonder if a hardware hack with a new soldered in usb-serial adapter to the NEMA output might be easier)
