Frequently Asked Questions - GMR7V1.2 MB QUART

How do I pair my phone via Bluetooth?

On your phone, search for devices and select GMR7V1. If a PIN is required, enter 0000. The unit will display a Bluetooth icon when connected.

Can I use Apple CarPlay wirelessly?

Yes, ensure CP Wifi is enabled in the settings (Other menu). Pair via Bluetooth first, then CarPlay will connect automatically.

What is the maximum USB drive capacity supported?

The manual does not specify a limit, but most USB drives up to 64GB (FAT32) are compatible. For best performance, use a drive formatted as FAT32.

How do I reset the unit to factory defaults?

Go to Settings > Reset. Touch Yes to confirm. This will erase all custom settings and restore factory defaults.

Why is there no sound from my external amplifier?

Check that the blue remote turn-on wire is connected to the amplifier's remote input. Also verify zone levels are turned up in the settings.

How do I connect a backup camera?

Connect the camera video feed to the yellow RCA (Cam1 or Cam2) and the trigger wire (pink for Cam1, purple for Cam2) to a +12V source that activates when in reverse.

My USB drive is not recognized. What should I do?

Ensure the drive is formatted as FAT32 and contains supported audio files (MP3, WMA, WAV). Try a different USB port (USB1 is for music, USB2 for iPhone).

Can I adjust the subwoofer level independently?

Yes, use the SUB+ and SUB- buttons on the front panel or go to Settings > Audio > Subwoofer to adjust level and low-pass filter.

How do I change the radio region (USA/Europe/etc.)?

Go to Settings > Radio Area and select your region. This adjusts the frequency step and band limits accordingly.

Installation

Wiring and Connections

• We recommend wire-to-wire connections such as power, ground, and speaker wiring are soldered and protected with either heat shrink tubing or high quality electrical tape.
• The main (yellow) power wire should be connected to a source with at least 10 amps of additional current capability to support the unit. This has an in-line 5 amp fuse for protection.

Preamp Level Audio Connections

- Zone 1, Zone 2, and Subwoofer RCA preamp outputs are labeled as such. These are intended to be connected to external amplifiers (not included).

• Subwoofer RCA outputs (green RCAs) are mono and paralleled. They are identical subwoofer audio signals. Their frequency range is controlled by the low pass crossover and the subwoofer level control. Both are found in SETTINGS (refer to Page 21). We recommend starting with 100Hz for the low pass crossover point.
• This unit offers zone control to balance the sound level between different zones. The zones are designated by the zone 1 & zone 2 RCA outputs (using external amplifiers). For example, if using in a boat, a passenger area can be designated as zone 1 and a wakeboard tower speaker could be designated as zone 2, allowing lower or muted volume in the passenger area zone 1 and more volume at the wakeboard speakers zone 2. Each zone can also be independently tuned to achieve the best sound output for different size or style speakers. Example, if the boat has 6.5in speakers connected to zone 1, the HPF may be set to 120Hz high pass to reduce distortion from low frequency reproduction and if zone 2 has 8in wakeboard tower speakers it can be adjusted to play a full range audio signal. (See page 21 for more information.) The volume knob will control both zones and the individual zone 1 & zone 2 buttons allow adjustment of each zone independently.(see page 8)

A full scale cutout template can be found at mbquart.com/product-manuals/

Please print the template out or use the provided dimensions shown below for easy installation.

Mounting Radio
