I've done just that. My Range Stop / Start defeat device arrives on Tuesday! It wasn't cheap, but if it works, it will be worth it to me, at least. I'll report back with my findings.I contacted Range Technology about their device and was told there's no difference in the systems, but they just haven't physically tested it yet on the later models and therefore can't guarantee it. I guess you'd have to buy one, try it, and return it if it didn't work.
