I've started installing a new stereo in my 05 LGT following the thread here: http://legacygt.com/forums/showthread.php/official-dual-hvac-double-din-jdm-kit-thread-113589.html
Here's where I'm at. After getting the harnesses at ae64.com (run by member SVXdc here) and soldering them appropriately/heatshrinking them, it's really a fast install. Only took like 5 minutes to get the trim pulled and the old radio out, then a few more minutes when I had to plug it back in to eject the 5 cds that were still in it
