Here's a thread from a different board regarding installing the empeg into an Isuzu VehiCROSS:
http://club.vmag.com/ubb/Forum39/HTML/000848.html

The VehiCROSS uses the same dash configuration as the '97 Rodeo/Passport, IIRC. I have a Kenwood eXcelon too.

Oh, if your dash is the same, then I strongly recommend against putting the empeg in the bottom DIN. Since I put the empeg in, I rarely need to look at or control the Kenwood, but I leave the full-screen info on on the empeg, and putting that on the floor would be a dangerous attention grabber when driving, even just to change tracks. That's just my $0.02.

Here's a picture of mine almost fully installed with the Z828 on the bottom:


The thread describes a couple ways to install it. On mine I bent the square side tabs out and drilled through the center of the dimple. It lines up perfectly with the bottom mounting holes of the stock brackets, but it'll be too deep into the dash, so I had to space it forward with washers. I can take pictures with the dash fascia off later if you like.

Regards, and good luck.
