Wow, you've got a pretty strong opinion there chief...especially when you seem to compare all of these nav units to the ONE in your Lexus.
If all of those aftre market units are so great.....how come you have owned several? I played with the nav in the Tundra and my Corvette has one. This past week a coworker and I were driving around in nashville and he was using a portable garmin deal...brand new, cost 500 bucks he said. it's detail and resolution was worse than the one in my vette (the GM is really good) Admittedly the japs prob have better nav systems than GM...The tundra's nav was cool great features, and I loved the map detail.
Also, you were very wrong on some things....
about my vette nav (which might not be as advanced as the toyoter nav):
-I can input POIs while driving, and I can scroll through upcoming exits and amenities.
-It shows roads in fields and does great with back country rural roads
-has never given me a wrong turn on rural roads from WA to GA
-It has seamless state-to-state mapping
-new disk is free...go to corvette forum and have someone burn a copy
++pros for a built-in unit
-it's coded and useless if stolen....not yours
-don't have to deal with a chunk of electronics blocking my view
-other vehicle systems displayed on screen
-integrated antenna
-no extra crap floating around my car/truck
-screen is bigger
-It's under warranty
-in the vette...the nav is integrated with the Head-Up Display and projects directions and route information on the windshield so I don't have to look away from the road...aftermarket won't do that biatch
yes, I have based my rebuttal on a GM/Corvette nav, but I have played with the new tundra's (as i previously stated)...the nav in my new tundra will be even better than the one in the vette (aside from the head-up display). I have also used (N)everlost in Hertz renatl cars for years and hate that stand-alone $h!t.
Before you point out all of those supposed, and often, fictional negatives, pllease be sure to be informed.
and now for something completely different::::
I wish that the voice on the nav was a bitchy british female that got exhasperated with me when I missed a turn....you know? Just like having a feisty woman sitting next to you, though without the potential for road-he*d.
