I went and bought the 107 today at radioshack. I was able to go through it and get to know how to use it. Now going to the advanced stuff like using the sd card on the computer i wanted to update the library and all that also edit playlist names by typing it in and not scrolling through everything with the up and down arrows. so i put the card in the computer and sure enough it wont let me copy anything to the card that i edited. I went ahead and did the prepare sd card for use and i formatted it and everything went well and i added everything i needed for frequencies from the new library. i save it all put the card in the scanner and i get fatal error "no file system on sd card" what the heck happened? I tried formatting again copying everything and still nothing. also the firmware, software, and library are all up to date i looked all over on here to see if anyone had this problem but had no luck. the only thing i can think of is to buy a memory card at the store and try to format that and use it
