I skimmed through the API docs earlier; I'm thinking to get a Garmin watch (primarily for my own running), but with one eye on possible development for it.
Q1: is there any model that is particularly better than others, for testing and development?
Q2: can I install my own apps on my own watch, before submitting it to garmin for approval for the app store? (E.g. upload over USB cable is possible?)
Q3: we have a lot of experience with Asian languages; I noticed a "ForeAthlete 235J", etc. model mentioned in the app store. I guess this watch comes with a Japanese font, and the same model number without a "J" does not? Are there any other differences in the "J" models? (What I'm really hoping is that they are exactly the same, and the "J" models just have different marketing and support; meaning I could test a Japanese app on my own watch.)
Thanks.
