TOYOTA TOUCH & GO SYSTEM DESCRIPTION
The Toyota Touch & Go system enables a suite of services on select DA (Display Audio) head
units on available Toyota models. The system will connect with the user's cell phone for the
provision of Location Based Services as well as the various applets such as Google search,
fuel pricing, parking information, weather information, Parking and Glass of Water, etc. Other
services will be launched in the future. A range of cell phones have been validated as compat-
ible - see
my.toyota.eu
for more details.
The system utilizes a USB connection for system software updates, navigation map updates
as well as access to a variety of USB media storage devices that use MP3, AAC, WMA and
WAV audio formats. The USB uses the 2.0 USB standards for connectivity. The USB port will
also charge a connected device.
