I installed a new Bestem topcase,a radio with wired remote and 4 Shark speakers on the Burgman this past week. All these were supposed to be Christmas presents but I could not wait. The radio is AM/FM,CD,weather bands and connection for MP3 player. It works pretty well and the wired remote is great. Have not had it out on the road yet but going for a ride tomorrow. Took me awhile to get it all figured out and installed and would have taken me just about as long to take it all apart and the put it all back on after Christnas. The wife wasn't to happy but she isn't happy nost of the time anyway.
