I should have gone for the S2 in the first place. I need the swim functions. I've got about 22 hours left on my eBay auction. I didn't set a reserve and it looks like someone is going to walk away with a steal haha. Anyway, on to my question. I will be able to use my S1 back up on the new S2, correct? I can do a new setup, but it would be nice if I can use that backup. I'm just not sure if they are interchangeable between Series 1 and 2. Thank you!
