Hello Miles,
We have the Alpine system (from Honda) in our minivan. It was much easier initially for us to use than the Pioneer. The touch screen is a great addition and also something missing from the Pioneer. The Pioneer does offer a lot more other gadgets though for a lot less money so I went the Pioneer route but the Alpine was certainly looked at. To much money for my empty pockets. Can you please do me a favor and tell me how many streets show up for Tyler Texas. The 2000 map DVD didn't offer but 7 or 8 streets. The website still indicates that Tyler hasn't been updated yet. My wife gets lost easily and I would get her a new DVD map if it would help.
I always hated driving out of town and getting lost before. Missing your turn off or generally worrying if you are going in the right direction. People can say whatever they want about any of these systems being expensive, they a absolutely worth the money. I now travel stress free. Who need Airlines anymore. With all the hassle now, I just drive, if it less than 6 hours away. I guess the way the Avalanche drives may have something to do with it also. Navigation will always be the first Mod I'll make on any new vehicle I buy.
