Has any body tried the 350 I just sold my 500 and got a 350 to replace it because of the size and weight of the 500. I know the 350 is not water proof but I have a Roady XM on my 1800 for a year and it never comes of f and with the high tech baggie for a rain cover it has never gave me any trouble. So as far as rain goes I can cover it up. But do you know if it will hold up. I used the XM so much that I never turned the MP3 player on and the 350 has almost as many ways to set it up as the 500 does plus a built in batterie. Has any body else tried this or heard of one being used. Thanks Larry
