New guy to the group and Im in east GA. I have a Rt680 I got used. I got to this group by looking for 680 to 700 modifications, if needed Other then wifi....I dont see much that is needed. Later.
Welcome. If your 680 has the original pointy lid stops and you will be using a cover, I'd recommend replacing them with the new style, or putting tennis balls over the points before covering. Either one will increase the lifespan of your cover. That's about the only mod I've made to my 680 (other than controller upgrades).
