BCD436HP curious question, got "file size is too big, up to 1M byte". message after upload.

Hey, got my favorites lists all set up (finally :)), and tried to load them into my `436HP, whereupon i got the following message, "file size is too big, up to 1 M byte". Question is, is this a function of a too-small SD card (in which case a bigger one would fix it), or is this a case of the scanner simply cannot process anything bigger than 1MB in size? If it`s just an SD thingy i can just go out and snag a bigger card, if it`s a case of the scanner can`t deal with anything bigger than 1MB then i`m kinda stuck. So, what of this? SD card fix? Or do i just live with it? Thanx! N9NRA P.S. Was finally able to pare down my favorites lists to get it to stop giving me that (error?) message, but i`m still kinda curious about it now. Thanx!
