Ok, I've searched and searched...but cannot for the life of me find what the D3's nav discs are called to download them. I only really need the West one, I never opened the East one as I live in Texas. It's around here somewhere, but not doin me much good.

 

Anyways...does anyone know what it's called? I.e. CNDV-70MTP (but the D3 version)?
