I had this one (Clarion NX501E) car-navigation 1-2 years ago :-) IGO Primo 2.4 is there working perfectly.

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.
