original SD-card with pre-formatted filesystem from Clarion.There is a special format (unknown by Google, ha ha) ! So, for 100% working iGO with no-sound troubles, you need: Warning ! Don't format your original Clarion SD-card because you will LOST the special format ! So, if you start to play any AudioCD or play any MP3 from USB-stick, you can hear iGO sound too :-D. iGO as third-party program know use standard audio-output and that mean USB-MP3 and/or Audio-CD audio-output on integrated SoundCard. iGO Primo of third-party (not branded by Clarion) don't know use the correctly audio-output of integrated SoundCard (just which is designed for iGO-audio-output only). Problem rests in sound card (non standard software & hardware). I was looking for a long time about this problem on the internet, but unsuccessfully. Sound of iGO can you hear only when you have playing any MP3 music from inserted memory USB-stick or when you have started and playing any Audio-CD. But the big problem is a sound card ! Original iGO-Primo is branded by Clarion as the revised edition and that's developed especialy for Clarion devices. I had this one (Clarion NX501E) car-navigation 1-2 years ago :-) IGO Primo 2.4 is there working perfectly.

I apologize if this is in the wrong forum. I think I might just need a map of how it is laid out, but perhaps even the files if that would be available. I stumbled across your website from Google, and I am hoping that perhaps someone will be able to assist me. He tried to tell me to rename the directory, because he wasn't for sure the exact order it went in, but he clearly doesn't know what he is talking about. I have the 'original microSD', but it appears the files have been messed with. I should file a complaint, and return the item, but I had already installed the headunit, and had it put in my car, so I didn't really want to mess with it. The individual I purchased the headunit from must have messed with the micro-SD files, and thus was the reason he listed it. I have a Clarion NX501 headunit that I purchased from eBay.
