Can't get it to recognize music we added on a new scan disk

Don't ride when listening.

The reason only some songs are playing is because the other songs aren't in a format that it recognizes. Make sure all the songs are in mp3 format, if they're not you can get programs that will convert any song into mp3. If you need more help let me know =)

First, many SD storage music players do not support HCSD. Is the SD card bigger than 2gig? This could be the problem. Try a smaller SD card.

I own the player on my 2004 HD Softail Deuce. I have a catalog of various sizes of sd cards from my original 64mb up to 2gb. The problem you are having could be that you have the music in WMI instaed of having converted it to the mp3 format with your windows player. Be sure to use the lowest quality when converting to the mp3 as you will not notice the difference in the playback. Also do not be surprised that you cannot get what you think on a 2 gig sd card. One of my 2 gig cards has the entire Led Zeppelin studio catalog including some various Robert Plant solo songs from his various albums. I buy my sd cards from Microcenter here in Ohio for around $7.00 each. The local wal-marts are making a killing with 512mb for around $15.00 each, so shop around for the cards you need.

You can go to www.signsbykines and find the complete instructions for the Harley HA90 MP3 player

reformatting the 1gb or the 2gb disk is a snap, but that won't fix your problem, here's how to reformat then I'll discuss the way to make a 1 or 2 GB work, first with the disk and also the reader that came with the Harley MP3 player just plug it into the usb port on your computer, then click start on the computer, then my computer, now you will see Icons for the A,D,E and F drive, the F drive being your storage device ( sound disk ) right click on this and when the drop down window appears you will see either fat or fat32, most likely it's already set to fat32, if not then change it to fat32, now just click on format, a drop down will tell you that all info on the disk will be lost, click O.K. and it will reformat the card.Now to get your Harley HA90 Road Tech MP3 player to read the card, the player will not read a card that has the soundtracks in a folder so you have to open the folder, I have explained the how to in another post on this site, so to save space try to find it, if you cannot then make a post to let me know

The WMA files are probably copyright protected, and this device was not set up to read them. I would try converting them all ot Mp3 format - you will probably have better luck. Here's the official Harley page that I found:
Here's the best bet - there are pdf instructions for upgrading the software and a few other functions, but no user's manual for it per se:

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!!!!

It has already been said that the Harley Road Tech MP3 player will not read song from a folder, I was having no problem with it reading up to a 512 mb disk, however it would not read 1gb or 2gb disk because for some strange reason the songs were put on the disk as a folder, so I figured this out, rip your soundtracks to the mp3 format using the windows media player program, then sychronize them to the disk, no click on start on your computer, then my computer, then with the disk plugged into the usb port you will see that icon, storage device F , dbl click on that and it will open a window and show a folder, dbl click on that anf it will open all the soundtracks, now go to edit in your task bar and then to select all, this will highlight all soundtracks, now go to file and then send to and send those soundtracks to the F storage device, after you do that then delete the folder at the top and your MP3 player will now play the songs

When I was looking at this product, I contacted the manufacturer and they made it clear the unit worked best with a 512 mb or smaller card. The problem is not with Sandisk or the SD manufacturer, it is with the HA90.
