Historically, I've done all my GPS routing on my phone (with it being inside a saddle bag or something). Recently, I remembered I had a Garmin Nuvi 40LM sitting in my vehicle, unused. What I would like to do is add it to a motorcycle, with a waterproof case. Additionally, I'd like for there to be enough room for me to fit in the 12V to 5V adapter required to power the GPS, with a panel mount SAE connector to get 12V inside the waterproof case. Does anyone have suggestions on a waterproof case big enough to fit all of this, and ideally be hard case (to facilitate easier mounting to a RAM mount)?
