Concern examples:



“We can’t get the clock to work and are unable to see it.”
“Clock is not keeping time.”
“Clock time is incorrect on new vehicle during PDI.”
NOTE: The UVO 3.0 platform is the first non-navigation head unit that has a GPS module for
date and time.
Specification:
“GPS date and time” on the UVO 3.0 will not
get “picked up” automatically on a new
vehicle or after a loss of power to the head
unit. It is necessary to set the date and time
in an area with strong GPS reception:
From the Home screen, select Setup →
swipe the screen to the left → Date/Time →
adjust date and time using the up or down
arrows.

Diagnostics:
Always test the vehicle in an open space with strong GPS reception. Do not test this
functionality in a garage or covered area.
If no time is shown (area is blank) or there are dashes where the time should be, check the
following:
1. Confirm vehicle has been driven in an open area and time is still not shown.
2. Measure the voltage on the center terminal of the coaxial connection at the antenna
base connector on the harness side with the radio and ignition on (spec: 5V to 6V).
3. If the voltage is not within specification, confirm the blue GPS connector is connected
properly to the back of the head unit and that the pin is not bent or damaged, and
continue to check circuit integrity from head unit to the antenna.
4. If voltage is within specification, consider a head unit replacement.
If the clock is confirmed to be losing time typically after sitting for a few hours or overnight,
check the software version of the head unit. A software improvement was incorporated into
production on July 18th, 2016 in software version V074 or later. Clock improvement software
is also being applied at the Mobis Remanufacture Center so head units ordered and obtained
through Direct Exchange will contain a countermeasure.
