I have a bad tuner in my UTV. I have a 4 year replacemnt garuntee. If I took it in, would they give me the version with the 3.7 software on it? I've heard it has lots of bugs with that version. I would prefer that I get either my unit replaired, or a re-furbished one with the 3.5 software on it. Does anyone thing that they can do that? I bought it at Best Buy.
