Tundra HV
CONDITION
Background:
The 2022MY Tundra and upcoming Tundra HV vehicles are equipped with a new generation of audio system, this system
uses an entirely new UI (user Interface) and hardware.
Items to note (these are examples):
-
Many services are cloud based. For example, the navigation is called Drive Connect and is entirely cloud based,
meaning it requires a subscription after the trial ends. This also means that in areas of poor cellular service, reduced
navigation functionality may be normal.
-
When a customer takes delivery of a vehicle, one of the first things they will do is connect to the head unit by scanning
a QR code to connect their account with the vehicle. This is equivalent to enrolling on a 17CY+ vehicle and will result
in the activation of remote services and the navigation function. The customer’s profile will load automatically when
entering the vehicle with a linked key or BT paired phone.
-
Audio units must NOT be swapped between vehicles except in rare cases when advised by FTS or TAS.
Swapping head units between vehicles can result in one or both head units becoming blacklisted (head unit
connected services will be inoperable).
-
Since the faceplate buttons are no longer located at the side of the display, a new method is used to enter the service
menu.

Applicability
RECOMMENDATIONS
Unable to enter
diagnosis mode due to
no hard buttons at left
side of screen.
Quick reminder:
1. Turn OFF the audio (not just volume)
2. Turn off the display in settings.
3. Swipe 5x to the right.
4. Swipe 5x to the left.
If the above does not work, please reconfirm that the audio is
OFF, not just volume turned down.
New method
Please refer to the Repair Manual for additional details:
AUDIO
AND VISUAL SYSTEM  DIAGNOSIS SYSTEM  ENTER DIAGNOSTIC MODE
(scroll down to “(b) Start method 2”)
Customer profile fails to
load when starting or
entering vehicle (popup
message displayed on
head unit screen at
startup).
Confirm that the customer smart key has been linked to the
customer profile using the head unit. This should be done at
vehicle delivery if possible.
Please see T-TT-0675-21 for details.
Notes:
- Linking can only be done after the customer is enrolled,
and their profile is loaded.
- The customer should consistently use the same smart
key to ensure loading of their profile.
New capability
Delete personal data not
present, or HU reset
cannot be selected.
Additional question:
When should this be
used for 21MM?
As mentioned, 21MM doesn’t have the same UI or functions
as previous generations.
There is no “Delete Personal Data” menu item.
There are two similar functions for 21MM, but at this time we
recommend against using them unless advised by TAS.
In addition – these may be greyed out unless the profile for
the primary user (e.g., owner) is actively loaded to the head
unit.
Expected
operation
Audio units were
swapped between
vehicles
Return the head units to the original vehicles and contact
TAS.
Do NOT swap head units between vehicles.

RECOMMENDATIONS
Software updates for
head units
Software updates for 21MM head units can be done via 3
methods.
1. (Primary) Customers will see an Over-The-Air update
notification on their audio unit. Customers would review
and accept terms and conditions and, in some cases,
would be required to connect the vehicle to an external
wi-fi network to enable the update to download.
2. (Secondary) Customers would download required update
file from https://www.toyota.com/firmwareupdates/download and install in head unit. In this case, to
reduce the size of the data downloaded, only the specific
files required for the customer’s head unit are provided.
3. Dealer backup method – dealers will have the ability to
perform an update by downloading data to a USB via
TIS. Data downloaded will be a “complete” update and
will include all required files. While this type of update
has less restrictions than the customer version, due to
update method this installation can take 45 minutes to
complete.
Expected
operation
Head unit settings or
presets change
depending on which
profile is loaded
This is expected operation that is enabled by user profiles.
This allows a customer to operate multiple vehicles and have
their preference follow them from vehicle to vehicle – if they
load their profile in each 21MM vehicle they use.
Expected
operation
Unexpected profile loads
If a user profile has been associated with a key fob, then it
may load in place of a guest profile.
Profiles can be switched via on-screen menus if desired.

operation
