The nav unit cost $1575. It's made by Denso, which makes all the Camry navs, I believe. It looks "factory" because it basically is.
While trying to decide which way to go, I also took a trip down to Cerritos Toyota to look inside the 2004/2005 4runners and sequoias and the nav screen looked the same. I wasn't able to try them out there, but the units all look like what I have. That helped my choice quite a bit.
I believe the "true" 4runner nav units are 2-pieces... a screen in the dash, and a base unit located in the back somewhere. The Camry unit is an all-in-one which is mounted in the double-din slot.
Initially, I wanted the Eclipse too, but the cheapest I could find it was around $2299 (retail) and $1900 (ebay). Many people don't know that the Eclipse nav doesn't carry the "theft" warranty like some of their other stuff. Don't believe what some Eclipse sellers say, there is NO theft warranty!(verified by Eclipse customer service). And it only comes with a 1-year repair warranty unless you have it installed by an authorized dealer... then the repair warranty is 3 years. The Eclipse is nice, but after taxes/installation at Goodguys (Ca), $2667 was too much for me! That's almost $1000 more for about the same thing... (less movie dvds, mp3)! Fujitsu-ten makes units for Lexus, so I've read, but word is the map DVD is the same one! Of course, I don't know if this is true or not, so don't take my word for it.
I decided that I would rather take my chances with Denso! So far none of my stock stuff has died on me yet. My other truck is a '93 Toyota SR5 pickup and that stereo is still rock solid. Junk, but rock solid! Of course, maybe I'm just lucky!
Good luck with choosing which way to go, I had a hell-of-a-time trying to decide too! But now, if I want some starbucks, all I have to do is program the POI and all the coffee shops where ever I happen to be pop up on the screen!
