New unit installed 2 days ago, just tried SD card slot, used a Kodak 4 GIG card,did not show up, found post saying all brands don't work went and got a Kingston 2 Gig which someone posted works,still did not show up,when I pulled both cards and looked at contents on card it shows a device.nng file and gpslog folder.

Do you have any music on the card?

No,just put blank in. Thanks for the heads up,didn't realize had to have data on card before it would show up.

SInce it is putting files on the card it is obviously reading, but for it to show in the A/V source list it has to actually contain something AVIC can play...
