Seriously - good tip. I've actually had pretty good luck at West Marine for GPS bits, they seem to have a good selection and many of the salesdrones actually have a clue about GPS.
Even more than that, they seem to have a company wide customer service policy that differs from the norm, they always jump in and try to find a solution. Dealt with them a lot over the years.
I think it stems from the fact that no 2 boats are the same, there's A LOT of one-offs out there, so they understand that it's gonna take some leg work to find you what you need. And that's their business, so they're good at it.
