Key Features

Front USB port, Front AUX input CD/MP3 radio tuner - JVC KD-R421

Made for iPod Works for iPhone MP3 WMA CD AM / FM Radio USB Aux input Stalk Control 1 Preout

JVC KD-R421 New for 2011

Classy design which will look at home in any dashboard, this highly featured FM, MW, LW Receiver and CD player will reproduce music from many sources. A front panel mounted USB port reads MP3 and WMA files from a memory stick while the neighbouring Aux input will reproduce sound from any external analogue input. A second Aux input on the rear allows connection of JVC's unique Bluetooth adaptor for handling hands-free calls and music streaming from a mobile phone or other Bluetooth enabled device.

Connect the optional JVC KS-BTA100 to either one of the two Aux inputs to expand functionality to include Bluetooth handling of calls and audio streaming. A mighty internal 4 X 50 Watt MOS-FET amplifier is supplemented by 2 pairs of line outputs, one of which can be switched to a subwoofer output complete with switchable high-pass filter and level control.

Inoperative radio
skhosana on 23/10/2014 3 star rating

what could be the possible cause for the unit to display 'check wiring then reset the unit'? and how do I go about solving this problem?

Dan on 24/01/2012 5 star rating

This stereo is a steal, very cheap for the features-I needed a stereo with a HPF (lets me filter bass out of my door speakers) and this was the cheapest I could find one. Sounds great, filtering the bass out of my door speakers has really cleaned up their sound and the sub out from this to my bass amp lets me raise or lower the sub independant of the rest of the music-you know there's always one track you need a bit bassier!!! Ordered it online, arrived the next day-best price and service, thanks:)

great service

i ordered one of these yesterday and it arrived this morning, my bf has fitted for me and I'm very pleased, sounds loads better than my old stereo and the USB func is great. Top marks to Car Audio Centre for their service and advice.
