I sold this unit because I am poor... but this is very good info and I hope others in the future will be able to use it. One thing I noticed about the 4Runner when I was in there looking around at things is how tidy everything is. The wires are all bundled nicely and easy to get to. The whole setup just seems like incredible quality.
I have been inside a lot of dashboards in my day and there is some real crap out there. Nissans are horrendous. I've worked on a lot of them and it just seems like they didn't care. Same goes with Suzuki, Dodge, and quite a few others. It looks like they took their time and thought things out when building and designing the 4Runner and that makes it so much easier to do modifications and deal with things like upgrading or fixing the audio system. I am highly impressed.
I did try the E7019 out for a couple of days and it was giving me audio directions and it seemed to know where I was and I never had those wires hooked up. I don't know how I got it to do all of that, but it was a pretty fun unit to play around with. Some of the features (like service intervals and such) were extremely cool. I wish I could have kept it and used it to its full potential. Now I'm back to the low end factory Pioneer stocker. How depressing! I'm tempted to buy one of those Urban Runner radios just because they are going for like $100 and they do navigation. Is that a horrible idea or what? I am sure it is.
