When buying a new car stereo it is important to consider how you are going to make sure the new unit blends in with your old car. Fascia adaptors are plastic, clip-on frames which blend your new head unit into the existing design of your car.Buying a new car stereo can be an integral part of upgrading your car. Whether you're after something with top sound quality, if you want to be able to listen to digital radio on the go, get better reception or an integrated DVD player, it can be an exciting purchase. Some people, however, are in for a nasty surprise once they've fitted the new radio; it just doesn’t look right. To fit your new stereo you’ve had to take off the fascia that surrounded the old one, and now it won’t fit back on again. A fascia adaptor can help. They’re available in both single and double DIN sizes and will help blend your new car stereo into your old car design.For the uninitiated, “DIN” is the abbreviation of “Deutsche Industrie Norm” and is, as the name suggests, the standard measurement for all aftermarket car stereos sold in the UK (if you don’t speak German, keep up). A DIN is 2 1/8 inches tall and 7 /18 inches wide - the depth is dependent on the design. A double DIN head unit is twice the size and is generally the dimension used by the more showy car stereos boasting LCD screens, SatNavs, DVD screens and the like.If your car radio socket is a standard DIN, then, yay, happy times, enjoy your new radio. If, however, it isn’t - and most car radios are not - then you will need a DIN adaptor kit or double DIN kit. These aren’t complicated; they fill in the empty socket left by the removal of your original car head unit, leaving a socket into which your new DIN or double DIN aftermarket stereo can be fitted. It's incredibly simple, handy and versatile.Only, it looks a bit odd. A bit sticky-outy, if you know what I mean. It doesn’t sit well with the rest of dashboard. You might have better sound, but you've cheapened the appearance of your car as a whole.Well, of course not. Your new car radio wasn't designed to fit in specifically with your make and model of car. It was designed to fit equally well into a Seat Ibiza, a Citreon C4 or a Ford Mondeo. You need a fascia adaptor. Each is simply a plastic frame that fits around the outside of the new head unit, blending it into the surrounding design of your car. The genius of the piece is its simplicity. It doesn’t obscure the display or controls of the stereo, but it does make it look smart. DIN and double DIN fitting kits allow you to fit an aftermarket car stereo without radically altering the appearance of your car’s dashboard. Fascia adaptors are available for a wide range of major car brands, including Peugeot, Kia, Smart, Volvo and Volkswagen.Please do note, however; some fascia adaptors will require you to buy the appropriate “cage” to hold your stereo and fascia in place. If this is the case, ensure that your fascia adaptor comes with the cage, as it could otherwise prove a headache to find a matching one. Quality suppliers of car stereo paraphernalia should offer this combination as standard where it is appropriate.If you want the best quality stereo for your car, but don’t want to sacrifice style and elegance, then you need a fascia adaptor. Like all great ideas, it is simple but effective. You don’t need any technical expertise to fit the adaptors, it’s a quick process and any small instructions you might need should be easily available online.
