Ok. I just got my F900 man this radio is so damn hard to mess with. Im better off with the kenwood. Any way if you want to change the slash Do these steps very easy.
1. Make sure u have the test mode loaded on SD card. If you dont go to search and type in Test mode and make sure its for the F-Series.
2.Take a pic or background you like and save it on your S.D Card as a Jpeg or Jpg.
3. Make sure the radio is off and Put the SD card in.
4. Let the radio read the test mode
5. Go to programs & click windows explorer
6. Then click on Storage card & open it up.
7. copy all the background & Pic you want by highlighting all the files you want with ur finger then to copy it click edit then copy same goes for paste.
8. click the back botton or file to go back to all your files and Click on My Flash Disk open that up
8. then click on Data open that up
9. Then click on splashpic. Then copy all the Pic or backrounds you want on there. "Yes" U can always go in and change them and delete them.
Now you done turn off the car and take out the SD card Now you have the Splash save into the radio setting. Enjoy..
