Boulder Trojan

I gave up on looking for firmware updates on the Pioneer website a year ago.  I can find the head unit and the install / manual uploads but that is it.  I looked through the FAQ's and hate asking newbie questions, but the unit has never had a firmware update and I wanted to know if it is worthwhile to keep on looking.

A direct link or location of the firmwarm file would be great.  Thanks in advance!

Not sure how fluent you are with a soldering iron but not having a usb on the back annoyed the hell out of me too.  I soldered onto the existing USB pin and ran shielded wires out the back (I think data wires needed to be flip-flopped).  Now I have a permanent connection to my iPod. When I disconnect it I can still use the front USB if someone in the car wants to play their tunes.
