Tech Tip: How to Set the Clock on Pioneer DMH, AVH, MVH & AVIC Models

Clock-setting behavior varies between Pioneer DMH, AVH, MVH, and AVIC receivers depending on whether the unit uses GPS auto-time, built-in navigation, or manual time entry. This guide explains how each group handles time adjustment and how to troubleshoot common issues.

Group 1 — Models With GPS Auto-Time (DMH-W / WT / WC Series)

(These units include a GPS antenna and use satellite time to automatically set the clock.)

Examples:
DMH-WT8600NEX, WT7600NEX, WT6000NEX, WT5000NEX
DMH-WT3800NEX
DMH-WC6600NEX, WC5700NEX
DMH-W4660NEX, W4600NEX
DMH-W3050NEX, W3000NEX
DMH-2000NEX

Clock Behavior

• Hour and minutes are automatically set by GPS

• User may adjust:

  • Date Format: d/m/y, m/d/y, y/m/d

  • Time Format: 12-hour or 24-hour

  • Time Zone: (UTC +/–)

  • Daylight Saving Time: (DST)

How to Adjust

Method 1:
Home → Settings → System → Date & Time

Method 2 (Quick Access):
Tap the on-screen clock to open Date & Time instantly.

Clock Settings Menu Example

Seasonal Time Changes

• Fall Back → DST Off

• Spring Forward → DST On
  (GPS handles all automatic corrections.)

Group 2 — Navigation Models with GPS Auto-Time (AVIC Series)

(Built-in navigation models always use satellite time.)

Examples:
AVIC-5100NEX, 6100NEX, 7100NEX, 8100NEX, 8200NEX
AVIC-W8400NEX, W8500NEX, W8600NEX

Clock Behavior

• GPS automatically sets the time

• User may adjust:

  • Time Format: (12-hour / 24-hour)

  • Date Format: (m/d or d/m)

How to Adjust

Touch the current time → adjust display formats
(Hour/minute cannot be changed manually.)

Group 3 — Manual Time Entry Models (AVH / MVH / DMH Touchscreen Models)

(These units do not use GPS for clock sync, even when a GPS antenna is included.)

Examples:
AVH-1330NEX
AVH-2500NEX
AVH-2550NEX
AVH-3500NEX
AVH-W4400NEX
AVH-W4500NEX
DMH-1500NEX
DMH-1800NEX
DMH-2660NEX
MVH-1400NEX
MVH-2300NEX
MVH-2400NEX

Clock Behavior

Manual entry required for:

• Year

• Month

• Date

• Hour

• Minute

Supports:

• 12-hour / 24-hour format

• Month–day or Day–month date format

How to Adjust

1. Tap the current time

2. Use ▲ / ▼ to adjust each field

Seasonal Time Changes

Users must manually adjust the hour (Fall Back / Spring Forward)

Special Note for AVH-W4400NEX and AVH-W4500NEX

These models include a GPS antenna, but the clock does not synchronize using GPS.
Time and date must be set manually.

GPS antenna functions support:

• Wireless Apple CarPlay

• Wireless Android Auto

• Location-assisted wireless features

• Faster and more stable wireless connections

GPS reception does not adjust the displayed clock.

Footnote — Why These Models Do Not Auto-Set Time

Even with a GPS antenna, the internal clock in AVH-W4400NEX and AVH-W4500NEX is not designed to use GPS time.
This is normal and expected.

As a result:

• Time and date must be entered manually

• DST must be changed manually

• GPS signal strength does not impact the displayed clock

Troubleshooting Clock Issues

System Information → Connection Status

Check GPS Status (Models Using Automatic Time)

A strong GPS signal shows multiple yellow and orange satellite icons.

If No GPS Signal or GPS Antenna Not Connected

The unit will not auto-set the time.

If the Home Screen Shows “— — — —”

This indicates NO GPS communication or a disconnected GPS antenna.

If the Clock Resets Randomly

• Check voltage on the yellow 12V memory wire

• Confirm the constant 12V fuse is supplying 10.8V–14.4V with ignition OFF

• Move the vehicle into an open area before testing GPS

Other Pioneer Models (DEH-S / FH-S / MVH-S Series)

(Non-touchscreen models with manual clock setting.)
