Another idea with an IDE/P-ATA cable
(2x20=40 pins), fortunately I didn't throw them away :

One side of the cable is connected to the Dock, and the other side to the Navigator PCB.
And yes, it's working !

Unlike my previous attempt, it could mean at the same time :
- reliable access to the Tx/Rx/VCC/GND pins
- without disabling the WiFi/Navigator features
But I'm going to need a short 3 connectors IDE/P-ATA cable. Unfortunately I don't have short ones and couldn't find any online. Short ones always have 2 connectors, as on the picture.
