Hey guys I am having a slight problem with my SD card and my AVIC-Z110bt. I put in the SD card and it seems that its not reading it because the SD card icon is not lit up or i cannot push to access it. It knows i put one in there because when i push the eject button it asks if i want to eject the SD card I entered. I'm confused. any help would be great. thank you.

My SD card is a 4GB Kingston

Are there any files on the card?

there are video files, and pictures

They may not be in the right format. If there not the card wont appear in the source list. There is a thread on here that details the best file formats for the unit.
