  • Rated 4.4 out of 5 by 5 reviewers.
    Rated 4 out of 5 by It was good Only needed half. Not sure why you gotta buy the whole lot. But yeah does what it needs to. 09 January 2016
    Rated 4 out of 5 by works as advertised works as advertised, though the amplifier remote wire is missing at the head unit end, even though it is present on the Bose adaptor and required to power up the Bose amplifier. Had to wire it in myself. 12 January 2015
    Rated 5 out of 5 by Great Guidance My son and I decided to change his car radio. Sourced the Pioneer unit we wanted and Halfords had a price match deal ! Decided to buy from them as they were local. The assistant got the radio from stock and spent 10 minutes talking to us about bits we may need, he said " if needed the item would be stock"..... Should have listen more closlely as I did need the harness... Thank you Halfords Winterstock rd, Bristol.. 05 January 2015
    Rated 5 out of 5 by Car Audio Leads The product was in stock and was perfect for the job as well as being reasonably priced 06 November 2013
    Rated 4 out of 5 by worked great but needed expert help for Porsche was advised in store that this was what I needed to install a JVC audio/satnav/bluetooth in my Porsche 911. It looked like it didn't fit so I took it back - with the JVC unit - but fortunately it was the store's audio fitting expert that was there and he worked out how I could fit it - I would never have known! Works a treat. A bit expensive for a few wires and a couple of sockets though!! 23 March 2013

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
