Bob,
Is there any drag on the battery from the OBDII connection after the bike is shutoff?
Not that I have seen. I have had my bike parked for up to 10 days with everything hooked up and it still started just fine. When I sent an email to Garmin asking about a parasitic drain on the battery they would only tell me the Nuvi was not designed for motorcycles. I did replace my battery this year, but I think that was just normal wearing out of the original battery after a few years. I can tell you 11.3v isn't enough to crank the engine over.
