Largest SD Card Size???

I've just purchased an HA90 player myself. I've read all of the troubleshooting forums and solutions, etc. My question is : what is the largest size SD card that will function with this player? Has anyone had success with a 4GB up to this point? (considering everything was correctly formatted, etc.)? Or is 2GB seem to be the most it will handle? Really would appreciate some feedback on this before I purchase new SD cards....... THANKS!

    i also have the road tec mp/3 player and it works just fine with the little 64mb sd card although i can only get 16 songs on it. so i purchased 1gb sd card from walmart and down loaded the sme songs from the same file and now the mp/3 player will not play them-----why ?

    i can bring the card back to the computer and it will play on windows media. i'm confused and need help, please.

I have a 1GB SD loaded and it works fine. Simply use the USB holder included and drag your MP3s in into it. No nesting, folders, etc. or it won't work. Picky...

I just purchased a 4GB SDHC Lexar. My computer sees it and I can put files on the disk. However, none of my handhelds will read it. So, I gotta take the thing back and get something smaller. Probably just use a couple of 1GB SDs instead of 1 big one. The 1GBs hold 10 hours worth easy. I can change them out each day on long trips. That's my 2 cents.

The largest sd card I can get to work in my ha90mp3 player is a 512mb, which will hold about 145 songs after I rip them to the mp3 format, if I rip them into the windows media audio pro format I can get about 580 songs on the 512mb card,
to get more volume out of the system download mp3 gain and follow instructions, you can bring your songs from a 84/89 db level to a 105 db level and gain a lot of volume

The 4gb cards are called SDHC(secure digital high capacity), check the packaging for the sdhc logo, if it just says sd your max size is 2gb.

I have a road tech ha90 digital music player . inserting a sd card with mp3 and wma format music . i get a erro message.

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.

Just bought 4GB SD card that hx4700 does not recognise - help pse

Your slot in the iPAQ is a SD slot, not a SDHC slot - therefore it will not read the card. Your PC card is probably a dual reader. The SD cards look the same but are different. Have a read of this...

Harley Davidson Road Tech HA90 SD card problem

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:!-608879135!hdijunapppr08.ihd.hd!7005!8005&HDCWPSession=43nTLxPTw2cyWmlLHvR8BY0pqGFrtc8n5f6GQL4PvhTDBmHHhWQP!1924091048!-135590298

HA90 MP3/WMA player

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.
