This came from bluetoot.pdf. I paid www.tundrasolutions.com $25 for a one-year membership. There, I was able to download the TCH owner's manuals & a lot of other related manuals. If you're trying to decide between NAV & non-NAV, I'd pay the $25 and read through everything. You'll get WAY more info than you are likely to find here. Anyway, here's just a snippet. I expect you will have to reformat it to make it readable. Sorry!


Bluetooth is a short-distance, high-speed wireless data communication system that uses the 2.4 GHz
frequency band prescribed by the Bluetooth SIG (Special Interest Group).
 This system enables drivers to place or receive phone calls using a cellular phone without releasing their
hands from the steering wheel.
 The Bluetooth hands-free system is installed on both the ’07 Camry Hybrid model with the navigation with
AV system and the ’07 Camry Hybrid model without the navigation with AV system as optional
equipment.
 The Bluetooth hands-free system of the ’07 Camry Hybrid model with the navigation with AV system can
be operated by touching icons indicated on the radio and player with display.
 The Bluetooth hands-free system of the ’07 Camry Hybrid model without the navigation with AV system
can be operated by turning or pressing the control knob of the audio head unit.
 The major difference between the model with the navigation with AV system and the model without
navigation with AV system is described in the following table:
