Possible unlock of Ingenix 81acrd unit?

Just looking to find out if it would be possible to unlock my P-81acrd by PowerAcoustik. It is a wince 5.0 device running Ingenix, 8" LCD Touch Screen 800x480 Resolution, Navteq Turn-by-Turn GPS Navigation. Map data is stored on external SD Card. Here is the product page for more info: [Please Register or Login to download file]

I'm having trouble with the Navitotal site today for some reason so I hope this gets posted. You might want to look at MioPocket regarding a possible unlock. There are different versions. Lite and full.
