So, I installed the PIE X3 this past weekend... In my Camry! I hope to get to the Trooper before next weekend. I did the Camry first because if it didn't work, I would know the problem was with the adapter, not the radio.

It works well. The only challenge is where to hide the display/ button unit.

I'll take pics as I work on the Trooper so I can post a full How-To.
