How to fix a Dual DMCPA70 Car Receiver that won't turn on?
If your Dual Car Receiver won't turn on, it could be due to several reasons: * The yellow or red wire might not be connected properly or have incorrect voltage. Check these connections to ensure they are receiving the correct voltage (11~16VDC). * The black wire might not be connected. Verify its connection to the ground. * The fuse might be blown. If so, replace it with a new one.
What to do if my Dual DMCPA70 Car Receiver has power but no sound?
If your Dual Car Receiver has power but no sound, it might be due to disconnected speaker wires. Check the connections at the speakers. Another potential issue is that one or more speaker wires are touching each other or the chassis ground. Make sure to insulate all bare speaker wires from each other and the chassis ground.
Why does my Dual DMCPA70 Car Receiver keep blowing fuses?
If your Dual Car Receiver keeps blowing fuses, it could be because the yellow or red wire is touching the chassis ground. Inspect for any pinched wires. Another possibility is that speaker wires are touching the chassis ground; again, check for pinched wires. Finally, ensure you are using fuses with the correct rating.
What to do if my Dual DMCPA70 has audio but no video?
If your Dual Car Receiver has audio but no video, it might be due to the parking brake safety circuit not being connected or the parking brake not being applied. Check the connections at the parking brake. Also, apply the parking brake.

Tips for SWI-RC programming.
The DMCPA70 is a media receiver designed for in-vehicle use, featuring Android Auto™ and CarPlay™ integration, along with a 7-inch digital TFT display. This device allows users to access various media sources, communication features, and navigation tools directly from their car's dashboard, aiming to reduce driver distraction by providing a streamlined interface for essential functions.
The core function of the DMCPA70 is to serve as a central media and communication hub in a vehicle. It supports a wide range of audio and video sources, including AM/FM radio, USB playback for MP3/FLAC files, and Bluetooth audio streaming. The standout features are its compatibility with Android Auto™ and Apple CarPlay™, which allow seamless integration with smartphones.
When connected to an iPhone, Apple CarPlay™ enables voice-control via Siri for music, navigation, phone calls, and messaging apps. Users can make calls, return missed calls, listen to voicemails, and view caller ID. Messaging functions allow sending, reading, and replying to text messages hands-free. Music can be accessed by artist, song, or playlist, mirroring the iPhone screen with relevant information. Navigation is powered by Apple Maps, offering turn-by-turn directions, points of interest, traffic information, and estimated time to destination. CarPlay™ automatically launches when an iPhone is connected via a USB port using an Apple Certified Lightning cable. While CarPlay™ is active, the unit's Bluetooth functionality is automatically turned off, with hands-free operations handled through CarPlay™. To exit CarPlay™ mode, users can either disconnect their iPhone or momentarily press the Power/Volume knob to return to the unit's main menu.
Similarly, Android Auto™ brings useful apps from an Android smartphone to the car's display, focusing on driving-related tasks. It supports Google Assistant for voice commands, allowing users to make calls, chat, read messages aloud, and send texts hands-free. Navigation features real-time traffic alerts, hazard avoidance, and route optimization. Android Auto™ requires the Android Auto app to be installed on a smartphone running Android Lollipop 5.0 or higher. When an Android Auto™ compatible device is connected via USB, Android Auto™ launches automatically. The device also connects via Bluetooth simultaneously. If five devices are already paired, the system prompts the user to delete a registered device. If Android Auto™ is active during a call on a non-compatible phone, the Bluetooth connection switches to the Android Auto™ compatible device after the call. Exiting Android Auto™ is done by pressing the Exit button or disconnecting the Android phone.
Beyond smartphone integration, the DMCPA70 offers standard AM/FM tuner operation with features like auto store presets, preset scan, and direct search keypad. USB operation allows playing MP3/FLAC files from a USB flash drive, with controls for track navigation, repeat, and random playback. Bluetooth functionality supports hands-free calls and audio streaming, requiring devices to be "paired" or authenticated. The unit can automatically connect to the last paired device if the auto-connect feature is enabled.
The device also includes auxiliary inputs for external audio/video devices and a rear camera input, which automatically activates camera mode when connected to the reverse lamp circuitry. Steering Wheel Control (SWC) input is compatible with PAC steering wheel control modules, allowing users to control basic functions like volume, track, mode, and Bluetooth calls directly from their steering wheel.
The DMCPA70 is designed for intuitive operation through its 7-inch digital TFT display and physical controls. The main menu, accessible via a dedicated icon, provides quick access to all operational modes such as Radio, USB, Android Auto, CarPlay, BT Phone, BT Audio, AV In, and Settings.
General operations include:
The settings menu, accessed from the main menu, offers customization across several categories:
The remote control provides an alternative means of interaction, offering buttons for power, volume, tune/track navigation, mute, preset selection, repeat, play/pause, talk, mode, end call, random, band, and voice activation.
The DMCPA70 incorporates several features and guidelines to ensure its longevity and proper functioning:
The DMCPA70 is designed with user safety in mind, particularly regarding video playback and mobile device usage while driving. It includes a parking brake lock-out feature that prevents video operation unless the vehicle is in "Park" and the parking brake is fully engaged. Users are explicitly warned against attempting to bypass this safety feature. Additionally, maintaining a low volume level is recommended to ensure awareness of traffic-related sounds.
