About the RetroSound Redondo RT

New tech for your vintage vehicle

RetroSound's Redondo RT digital media receiver merges modern car stereo technologies with a nostalgic factory radio layout. You can choose from optional push button kits that allow you choose radio station presets, while an umbilical cable attaches the kit to the radio chassis that mounts behind the dash. (You'll choose your push buttons on the way to the Cart.) So, you get old-school looks with a bevy of new-school features, such as Bluetooth®, USB inputs, iPod® control, and a variable color display – all without cutting your dash.

Hands-free calling and digital sound

You can talk hands-free or stream audio programming to the receiver with your smartphone, and you can connect your iPod or USB thumb drive to the two rear USB ports. You'll find two auxiliary inputs on the rear of the receiver for other sources, like a portable audio player. The Redondo RT also offers excellent AM/FM reception, and the built-in Radio Data System (RDS) enables it to display song titles from any radio station that's broadcasting text information. If you're looking for radio stations that won't fade away as you leave the city limits, add a SiriusXM tuner (not included) to this stereo to enjoy satellite radio's deep programming from coast to coast.

Looks and connectivity

This RetroSound receiver features six preamp outputs that make it easier to add amps and subs to your vehicle. You can adjust your bass from the driver's seat using the subwoofer level controls and variable low-pass crossover. Here's another cool feature that enables you to customize your look — you can choose from 32,000 backlight colors so the LCD display will look just right in your dash.

Make it a complete RetroSound system

Wanna add some serious power to your ride? RetroSound offers strong amplifiers to get the most impact out of your speakers and subwoofer. They also make low-profile car speakers that fit into a wide range of older cars and trucks, so you can be sure that your sound system will do justice to your vintage vehicle.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

This digital media receiver will not play CDs.

    Shaft-Style Radio

    Vehicle Compatibility: RetroSound's Redondo (M4) radio is made for vehicles with dash fascia separating radio dial from push-buttons, such as mid-60's to mid-70's Mopar, and mid-60's Ford vehicles with deluxe dash.

    Standard Knobs or Thumb-Roller Controls: The Redondo (M4) is the only radio to feature either period-correct shaft knobs or thumb-rollers and an independently adjustable push-button assembly specially designed for Mopar & Ford vehicles.

    Infinimount System: The Redondo (M4) radio features RetroSound's Infinimount System. In this design the shaft knobs or thumb-rollers and the display face are not permanently mounted to the unit, but instead connect to the unit via a harness so you can space the radio's shaft knobs or thumb-rollers at various distances from the chassis of the radio, as well as mount the face independently from the chassis body using the supplied mounting brackets.

    Variable-Color LCD: The RetroSound Redondo (M4) features variable color display illumination. You can choose from one of 32 preset colors, have the unit scan through all 32 preset colors continuously, or customize your own color (RGB; 0-9). The custom setting allows you to individually adjust the intensity of Red, Green, and Blue (from 0-9) to better match your vehicle's interior lights. You can also adjust the brightness of the display from High or Low. The unit's front-panel display offers an enhanced viewing angle and is daylight compatible. The LCD will display clock, audio settings, tuner stations, and song/artist information from USB and iPod/iPhone.

    Variety of Sources

    Built-in Bluetooth: The RetroSound Redondo (M4) is equipped with built-in Bluetooth (HFP/A2DP/AVRCP) allowing you to make and receive phone calls wirelessly through the receiver; as well as stream music wirelessly from your Bluetooth-enabled smartphone to the head unit. Before using your Bluetooth enabled device, it must be paired to the Redondo (M4). You can only pair one device at a time with this unit. Once paired, when your Bluetooth device is in close proximity to the RetroSound receiver, the auto connection function automatically connects the two units. The Redondo (M4) is compatible with most Bluetooth enabled mobile phones, including the Apple iPhone & Android smartphones.

    • Hands-Free Communication: The Redondo (M4) allows for wireless communication between the head unit and your Bluetooth enabled cell-phone. You can answer an incoming call from the head unit's front-panel control knobs. Incoming phone call information will be displayed on the unit's front-panel LCD and your music will be pause or muted. You will still use your phone to dial a phone number and then the call will transfer to the RetroSound radio. Use the included external microphone to speak into during your phone conversation, while the other party will be heard through your vehicle's speakers.
    • Wireless Audio Streaming: The Redondo (M4) also allows you to play back stored music and  music apps from your Bluetooth-enabled phone or personal music player using a paired Bluetooth connection. Playback controls included Play/Pause, Stop, & Next/Previous Track. This unit does not display song/artist information from Bluetooth audio devices.
    Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the RetroSound Redondo (M4).

    Dual USB Ports: The RetroSound receiver features two USB (type-A) ports connected to its rear chassis by a 40" pigtail. The USB ports enable connection of  portable USB mass-storage class (MSC) devices; such as a portable digital audio player or USB thumbdrive. Once you've connected your compatible USB device, the head unit will find your songs instantly and automatically start playing them. This unit supports MP3 (128 kbps +), WMA (64 kbps +), and FLAC music files in format FAT and FAT32. The unit can recognize a maximum of 999 songs/files (files will be read in order of creation and not alphabetically or numerically).

    • Controls: You will be able to control basic playback functions of your music files such as Play, Pause, Skip Track, Intro Scan, Repeat Track, and Random.
    • Display: The receiver also supports ID3-tags/WMA-tags for song/artist information. 
    • Charging: USB portable audio players that can be charged via USB will be charged when plugged into the receiver's USB port (max. 0.5A), and the vehicle's ignition switch is set to ACC or On.
    Notes:
    • Not compatible with Android mobile devices.
    • You cannot connect a USB device via a USB hub or Multi-Card Reader to this unit.

    iPod Direct Connection: Either rear-panel USB port can act as an iPod/iPhone high-speed direct connection when used with the USB/iPod cable that came with your iPod/iPhone. The USB connection allows your iPod/iPhone's stored music and music apps to be loaded instantly to the unit and sound quality to be maximized through the head unit's 1-bit D/A converter. The RetroSound Redondo (M4) supports audio playback of stored music or music apps, music navigation, information display, and charging of select iPod/iPhone models.

    • iPod Control: You can control your connected iPod/iPhone from the head unit's front-panel control knobs. You can browse your iPod/iPhone's music by Playlist, Artist, Album, Song, Genre, Composer, or Podcast.  In addition, you can activate Repeat playback modes (all/track). Most iPod/iPhone device's clickwheel or touchscreen will be locked during connection (Apple devices w/ iOS 6.0+ will stay unlocked).
    • iPod Display: The Redondo (M4) will display your iPod/iPhone's music file information from stored music. The head unit will display Track number, Elapsed playing time, Artist name and Song/Album title.
    • iPod Charging: The unit's USB connection provides 0.5A of current to power and charge your connected iPod/iPhone when your vehicle's ignition switch is set to the 'ACC' or 'On' position. This unit does not charge the iPad. If your iPod/iPhone has no initial battery charge, then the unit will not recognize it.

    Dual Auxiliary Inputs: The universal shaft-style receiver features two 3.5mm auxiliary inputs connected to the rear chassis by 7" pigtails. The Aux inputs provide a connection for portable external audio sources such as a MP3 player or  CD player.
