The motherboard is the lowest replaceable unit, so users cannot simply replace the charging port. Garmin permanently attached the charging port to the motherboard. If a user needs to replace the charging port, the user must replace the motherboard.

It's not a "Charging Port Replacement", it's a whole motherboard replacement, described in this guide. That's not what I'm looking for, and it's not what the guide's headline suggests.
Yes, you are right!
I was hoping it will go into SMD soldering/desoldering (using hot air, etc). Where would you find a new “motherboard”, anyways? At that point it becomes difficult to see the value in “fixing” the device.
BE VERY CAREFUL WHEN OPENING YOUR GARMIN - IT IS EXCEPTIONALLY EASY TO “TEAR” THE YELLOW FLEXIBLE CONNECTOR IF YOU ARE NOT AWARE OF THIS CONNECTOR -THEN THE GARMIN IS SCRAP - I find that the charge socket is the weakest point on these units & before I opened my last unit I threw a few out because the charge port had been damaged. The USB type C charge port can be replaced with a spare bought from an electronics part supplier, I found that I reinforced the port onto the board by soldering resistor leads to the USB socket casing & then soldered the other side onto the board to support also adding a some of glue from my glue gun. Seems that this modification increases the durability & lifespan of the unit. I also think that if the port gets damaged again I might try do a modification on the port & try solder the charger cable directly onto the board but be warned, because of the traffic antenna built into the cable I have no idea what effect this may have on the traffic function, possibly worth a try.
