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.)

How to Set the Clock

  1. Power the unit OFF (hold SRC)

  2. Hold the M.C. (multi-control) knob → “System” appears → press M.C.

  3. Select Clock Set, choose 12H or 24H

  4. Adjust Hour → press → adjust Minutes

  5. Hold M.C. to save

    7. GENERAL TERMS

    • 7.1 Governing law.  If You are a resident of any European Economic Area (EEA) member state, this License is governed by and will be construed in accordance with Belgian law. If You are a resident of the United States, this License is governed by and will be construed in accordance with the laws of the State of California, U.S.A. If You are a resident of Canada, this License is governed by and will be construed in accordance with the laws of the Province of Ontario and the federal laws of Canada. If You are resident of any territory outside the EEA, United States, or Canada, this License is governed by and will be construed in accordance with the laws of Japan.
    • 7.2  Jurisdiction.  The parties will use good faith efforts to resolve amicably any dispute or controversy that may arise out of or in relation to or in connection with this License, or any breach hereof. In the event no amicable settlement can be reached, if You are a resident of an EEA member state, the parties can choose to finally settle all claims arising out of or relating to this License (including its formation, interpretation, applicability, enforceability, performance and breach) by binding arbitration. If You are a resident of a territory other than an EEA member state, all such claims shall be finally settled by binding arbitration as provided herein. If parties agree to settle claims by arbitration, such arbitration shall be conducted under the arbitration rules of the International Chamber of Commerce by three arbitrators designated in accordance with those rules. If You are a resident of an EEA member state, then the arbitration shall be held in Brussels, Belgium, in the English language. If You are a resident of the United States, then the arbitration shall be held in one of three regional venues (New York, New York; Dallas, Texas; or Los Angeles County, California). If You are a resident of Canada, the arbitration shall be held in one of three regional venues (Vancouver, BC, Toronto, ON, or Quebec, QC). If You are a resident of any other territory, then the arbitration shall be held in Tokyo, Japan. The award of arbitration will be final and binding upon other parties and will have the reasoning therein. For residents of EEA member states, in case the parties do not agree to settle claims through arbitration, the Belgian courts shall have exclusive jurisdiction to settle all claims arising out of or relating to this License (including its formation, interpretation, applicability, enforceability, performance and breach). For residents of Canada, if the arbitration provision is not enforceable, the parties submit to the exclusive jurisdiction of the courts located in the city of Toronto, unless otherwise prohibited by law.
    • 7.3 EXCLUSION OF REMEDIES. TO THE MAXIMUM EXTENT PERMITTED UNDER APPLICABLE LAW, IN NO EVENT, EXCLUDING PIONEER’S WILLFUL MISCONDUCT, GROSS NEGLIGENCE, OR IN THE EVENT OF THE DEATH OR PHYSICAL INJURY OF THE USER AS A RESULT OF THE ACTS OR OMISSIONS OF PIONEER, WILL ANY OF PIONEER GROUP OR ITS THIRD PARTY SUPPLIERS OR LICENSORS BE LIABLE TO YOU OR ANYONE ELSE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES OF ANY KIND (INCLUDING, WITHOUT LIMITATION, LOST DATA OR ECONOMIC LOSS) ARISING OUT OF OR IN ANY WAY RELATING TO THIS LICENSE, INCLUDING YOUR USE OF OR INABILITY TO USE THE SOFTWARE REGARDLESS OF THE CAUSE OF ACTION ON WHICH THE CLAIM IS BASED, EVEN IF PIONEER GROUP OR ITS THIRD-PARTY SUPPLIERS OR LICENSORS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR CLAIM.
    • 7.4 LIMITATION OF LIABILITY.

    • 7.5. YOUR SPECIFIC RIGHTS. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF DAMAGES OR LIMITATION OF LIABILITY, SO THE ABOVE EXCLUSIONS OR LIMITATIONS, TO THE EXTENT PROHIBITED BY APPLICABLE LAW, MAY NOT APPLY TO YOU. YOUR SPECIFIC RIGHTS MAY VARY FROM JURISDICTION TO JURISDICTION.
    • 7.6 ESSENTIAL PURPOSE. UNLESS LIMITED OR MODIFIED BY APPLICABLE LAW, THE FOREGOING DISCLAIMERS, EXCLUSIONS AND LIMITATIONS APPLY, EVEN IF ANY REMEDY FAILS FOR ITS ESSENTIAL PURPOSE.
    • 7.7  Severability and Waiver.  If any provision of this License is held to be illegal, invalid or otherwise unenforceable, that provision will be enforced to the extent possible or, if incapable of enforcement, deemed to be severed and deleted from this License, and the remainder will continue in full force and effect. Any waiver of any breach or failure to enforce any provision of this License will not be deemed a future waiver of such term or a waiver of any other provision.
    • 7.8  No Assignment. You may not assign, sell, delegate or otherwise transfer this License or any rights or obligations under it, without Pioneer's prior written consent. Pioneer may freely assign or transfer this License or any of its rights or obligations under it.
