Hi Guys,
Trying to install a subwoofer onto the factory Garmin screen/headunit but can’t find a pin-out diagram for the headunit. I can trace speaker wires by their colours but not sure on the power and ground connectors.
These details are on a sticker on the unit
Model - Garmin
Part Number- 39920-61m52
ID- 61MA
Type- Fuji
Any help is great
Thanks
