RECOMMENDATIONS/EXPLANATIONS:
Smart Accessory delay:
The delay occurs when customer pairs a phone > starts a phone call then turns off the ignition off
during the call. As a result, the normal accessory delay time of 3 minutes changes to 10 minutes,
as long as the phone call is active and unless a door is opened. If a door is opened, the procedure
continues from action „Door open“ as shown in the diagram above.
What would happen if the ignition was turned on at certain points during the shutdown
procedure?
1. Radio would stay on and get active.
2.
HU would complete the shutdown procedure and then start up again > it could take up to 15
seconds until the radio turns back on.
Critical point:
If driver shifts into reverse during this period, the shutdown process will stop
(Reverse Camera delay) > if shifted back out of reverse, the HU will continue the shutdown process
and only show the reverse camera screen. During this time frame, no other features will be available.
CONDITION# 0.10:
Restart vs. Factory Reset:
RECOMMENDATION:
1.
Restart HU by holding the volume button and select button for
10 seconds
. This forces a
“cold” boot > there is no ordinary shutdown procedure.
2.
Factory reset: by clicking Factory Data Reset in Settings > Factory reset should be the last
thing to try. Only for use in serious cases as it clears the following settings/data:
• Radio presets
• Paired phones
• Phonebook data
•
Driver Profiles
• Synced media device data
• Navigation sensor calibration
• Parts of the settings go back to default
