Just got a new Garmin Zumo 396LMT-S GPS, and I’m attaching its mounting hardware, cradle, and power cable to my ‘84 R100RT. Is there going to be a parasitic draw from my battery by the cradle or GPS that I should be cognizant of when I’m not using the GPS? I don’t need a GPS often to navigate, and if it’s going to be a significant power suck on the bike’s modest OE charging capabilities and battery, I could leave it un-wired, and just run it when needed off its internal battery. Any advice from the experienced farkle-adders out there would be helpful. Thanks.
