My unit is the H-D unit that mounts in conjunction with the right hand controls. The manual does not say anything about a max size for the card. It does give a customer service # and e-mail. I sent them an e-mail and received the reply to call customer service at the same # that's in the manual! Ten minutes on hold is my limit. So looks like it's going to be easier to just pickup a 1gig card and give it a try. Thanks for your efforts guys!
Generally, MP3 players like most SD mem card devices come with software that only maps out to support a maximum size. My printer only supports 1G memory cards as an example. Only alternative is contact OEM manufacturer and find out if it is limited by the hardware or if they have a software/firmware patch download to upgrade the capacity. Good luck, I had 50/50 response...one manufacturer had a download, other said it was 1G max. :no
