This is J&M's part # JMDM-GL18. It will work on all GL1800s. It works great using a 4GB Flash drive loaded with mp3 music files. You can select songs and "tracks" using the CD controls of the Goldwing. Installation is relative easy. I am selling for a friend who needed the Bluetooth model. (He owns a business and needs to occasionally receive calls when riding.) That is the reason for selling. Price is $80, shipped by priority mail to the lower 48. Call 252-362-2329 or send an email. Can accept PayPal or money order.
