Upon shopping for USB jack for Clarion NX700, I found great USB jack online. Google the following, l-com ECF504-12AAS (since I am newbie, I can't put hyperlink unfortunately.) I figure whoever installed aftermarket HU with rear USB Port would be mighty interested in this. Especially those who own II or III w/o navi. as you see on the website, one end is Type A male and the other Type A female in coupler. I paid about $18 with shipping. I will post pix along with other upgrades(HU upgrade, HID, Fog lights & Backup Camera) once arrival of all parts and installation.
