OEM HiFi

Cantaloupe Radio has been OEM HiFi's Bluetooth retrofit partner since the first MDeck solution I demoed at The Vintage back in 2017. We are are pleased to announce that OEM HiFi has acquired the BA30 product portfolio we know so well. We will continue the support, manufacturing and future development of these products for the foreseeable future, with a specific intent to expand the availability of these products for a broad range vintage radios.

OEM HiFi also plans to contribute to the upcoming RS1 open source effort, and expects it to play a major role in enabling state of the art functionality for vintage radios.

After years of developing Bluetooth retrofit solutions for vintage automotive radios, the Cantaloupe Radio product line has transitioned to our longtime service partner, OEM HiFi. OEM HiFi has worked closely with the product line for years and will continue sales, customer support, warranty service,...

Cantaloupe Radio does it again... introducing the new RS-1 bluetooth integration kit. Professional install required, but retain your OEM radio's cassette deck. Expanded radio support including E36 radios like the C33, C43, CM5901, CM5903L, Mercedes CM2191

Reach out to me at [email protected], or Cantaloupe Radio.

At Cantaloupe Radio, we engineer products to seamlessly integrate modern audio tech like Bluetooth audio streaming, phone calls, and voice assistance right into the OEM radios of emerging classic cars. Because let's face it - aftermarket, chromed-out head units are hideous.

Designed some no-cut harness adapters and E30 kick panel spacers for the Focal 130AS component speakers. Many thanks to Kevin Basdeo for trusting me with the audio install in his beautiful Mtech2 convertible. He has also installed Focal ACX130 coaxial speakers to replace the very basic rear speakers the E30 convertibles came with.

Check out his posts on R3VLimited and E30 Convertibles North America for more pics and details!

Customer installed one of our refurbished 5908s in an Touring. Fun assisting them with a plug-in harness adapter. The Tourings were all late model cars with an E36 style 17 pin connector for the radio
