I thought I would post this here under the title of "Techstream" in case some don't make it to the other thread where the Techstream was talked about.
If anyone is interested, you can pick up one of these Techstream Units for less than $30.00 on Amazon.
I've just scratched the surface of what you can do with the unit, but here are a few of the "Customizable Settings" you can alter:
Wireless Door Lock
Smart Key / Access
Tilt & Telesco
I was also able to check the "Health" of several other systems on the vehicle.
I'm unsure what Lexus charges to connect to their unit, but for thirty bucks, I give it
Just thought some may be interested.
