The HMV SMITHS Radiomobile 4200 is a rare and highly sought after radio from the early to mid 1950's.
Finished to an exceptional standard, the radio has undergone a full cosmetic restoration and is equipped with an AM/FM 4 x 45W RMS Stereo radio and wired AUX input. All the original controls are serviced and integrated. The resulting radio looks and operates exactly like it should as a period correct device, but has up-to-date features and performance. Turn it on and it sounds superb!
The radio is 12V Negative earth unless another configuration is selected before checkout.
Additional options may be selected for increased functionality:
Bluetooth Full, totally legal, hands free telephony, audio streaming and voice control
USB Charges phone, tablet or laptop AND plays MP3 files from a USB memory stick
DAB/DAB+ Receive DAB stations on your classic radio
Please Note: If purchased for use in the US we will substitute an HDR (High Definition Radio) unit for the DAB/DAB+ converter for at no extra cost. Simply select the DAB / HDR option as normal and we will make the necessary adjustments.
All of these additional options are fully integrated into the radio, so the existing radio controls are used to handle phone calls or move between audio tracks etc.
This radio will be built to order according to your specifications.

Please allow 4 to 6 weeks form order for us to complete the work and ship your radio to you. We'll keep you informed of progress along the way.

Your car will have either a 6 Volt or a 12 Volt battery and it will be either Positive earth or Negative earth. We need to know the voltage and polarity of your car so we can build you a radio that will work in it.
Our standard build is for 12 Volt, Negative earth vehicles. If yours is NOT 12V Negative earth you will need to select the appropriate Voltage and Polarity from the drop down box and we will build a converter into your radio so it will work correctly in your car.
Check your battery, or ask an engineer if you're not sure. Polarity refers to which terminal of the battery, positive or negative, is connected to the car body, and hence is the earth or ground terminal.
The converted Radiomobile 4200 can be used with up to 4 speakers, each driven by one of 4 separate channels in the upgrade. However, it will operate perfectly well with the number of speakers you feel is correct for your car. If you use only the single speaker already fitted to the radio, the unit will automatically blend Left and Right Stereo channels into a Mono feed so there will be no compromise in sound quality. Each time the radio is turned on it checks to see if there's a speaker attached to each channel and any unused channels are automatically switched off. This means that an additional three speakers can be added without having to re-configure the radio in any way.
We would always recommend that new speakers are fitted with your converted radio. Go to our Accessories section to select from the high quality speakers we have on offer there.
Our AM, FM and DAB radio upgrades have all been optimised to operate using the original period aerial on the vehicle. No additional aerial, other than the original, is required.
Please make sure the original aerial is functional and if telescopic, it's clean and operates smoothly. If you need to source an aerial, we have a number of options available depending on the age and type of car and whether you want hidden, in-cabin or a powered aerial. Check out our aerials in the 'Accessories' section here.
A comprehensive installation and operating guide is supplied with every radio. This guide will be tailored to your individual set and will include full instructions for the operation of the radio, including any installed options.
Installation is straightforward, but we always recommend that it is carried out by a qualified and experienced engineer. However, if there are any issues or questions raised during installation we are happy to help, so please do get in touch.
Your re-engineered and upgraded radio is covered by a comprehensive 1 year warranty from the date of service.
Please be aware that our warranty is offered on the understanding that the set has been correctly installed in accordance with the installation guide supplied and has not been tampered with in any way.
If you have any problems with the radio at all, please do get in touch and we will work with you to find a resolution. Many issues can be solved on the phone, but if we do need to have the radio returned, we will arrange a collection at our expense. All you have to do is package it securely and hand it to the courier. We will repair the set and get it back to you as quickly as we can.
Because we focus on attention to detail and quality in everything we do, we have rarely had a radio returned. Consequently, we feel confident in offering our customers this comprehensive 1 year warranty. We want you to have total confidence in us and peace of mind when you purchase and enjoy your classic car radio upgrade.
