Hello, in the top right of the MicroSD card slot, there are 8-pin row.
1 -
2 - Tms
3 -
4 - Tdi
5 - Gnd
6 -
7 -
8 - Tck

I think the order of the pins is the show.
I think it is a standard JTAG connector on garmin gps.
Jtag_finder Mode Testing and coments us the results.

Another option, is to be the connector on the top left of the PCB.
An 8-pin connector. Check if pin 5 is Gnd.

A greeting.
