I emailed them and they only seem to have one for the E-Glide with a aftermarket radionI have the stock HK radio and just got my bike back out of the shop after having the radio replaced...got wet on a ride and lost the display. Radio still worked but no display...just a nice red glow. The servive guy told me it wasn't the first RG to have had this and I think in some other threads here you will find the same.
As for a cover I think the folks over a eGlideGoodies now have a cover for us. Haven't ordered it yet but I will have it before next riding season.
