Hi Eugene, thanks for commenting.
It is actually not a factory navigation radio, it is something different.
It can be a photoshop. I found this on ebay, so not sure what it is. Does not look like Denso or JBL to me.
There are quite a few of these units being manufactured in China. They're car PCs designed to look like the stock Camry system. I've found a few suppliers in China that sell these (I import electronics from China), but I'm not really that interested in them because they're basically a PDA with a large screen (specs are usually Samsung processor, 64MB RAM, Windows CE, etc.). I'd rather have desktop components or laptop as my car PC.
