SOURCE: Road Tech? HA90 MP3/WMA? Digital Music Player

My husband hooked one up with Kuryakyn speakers (amplified). BUT - we CANNOT get the music on the card...Windows seems to not like the idea of synch-ing without folders and the MP3 player cannot read folders... I'm pulling my hair out over this!!!!

Are there any upgrades for the Harley Davidson Road Tech HA90?

Not really, The problem with the older radio is that the way they fed the power to the mp3 side was to back door it through the FM modulator, thus resulting in a lower volume than theradio. Unfortunately there is no fix for it.

Cruise quit. brakelight stays on! on 1998 ultra classic

This is going to be a problem with one of the brake switches, most likely the switch on the front brake lever. The switch generally has slipped out a bit and needs readjusting, or corroded slightly on the inside and needs cleaned and lubed. What's happening is the brake switch is on, as if the brakes were applied, and the cruise's automatic disengage function when the brakes are applied is kicking in and not allowing the cruise to work.
