One popular product for self-fit is the Vauxhall retrofit Bluetooth kit for CD300 and CD400 radios.

We have made some videos to help any DIY fitters, they show the radio removal and refitting method as well as the best position for the microphone with two options (A-Pillar or Centre roof). We hope you find these useful and although we have got it down to about 45 minutes it might take you a little while longer but with very satisfying results. There are even some trim removal tools available to make it even easier.

All the above-listed products are among the world's largest manufacturers of premium car audio, navigation, and information systems, speakers, subwoofers, amplifier and audio accessories. Their strict warranty policy protects you, our valued customer, and our unparalleled reputation for quality and service excellence.


These products are sold in the United Kingdom through an exclusive network of Authorised dealers selected by Alpine and Four Car Audio. The complexity of today's automobiles and the sophistication of these products require a knowledgeable dealer to aid in the selection, integration and installation of your system. Dealers have been specifically chosen for their ability to present and install the products and have the ability to maximize their performance in your vehicle. The warranty policy covers only products purchased through our Authorised dealer network. Therefore, we assume no responsibility for products purchased through unauthorised dealers or internet sites. Only dealers listed in the Store Locator section of Alpine and Four website are Authorised to carry and sell the products.

Prior to purchasing any of these products, you should confirm if a dealer is authorised to sell or install the current range of products. Click on "Store Locator" on Alpine website product pages or Four Master page. This will give you a complete list of all authorised dealers you can purchase current products from in your area. Some of these dealers may have internet sites through which they are authorised to sell our products, check Prior to purchasing any product, confirm if a dealer is Authorised to sell or install current products.


Unfortunately, from time to time, products are sold by dealers or internet sites that are not authorised. Products sold by these unauthorised companies were not purchased directly from Alpine or Four Car Audio products sold by unauthorised dealers are sometimes:

  • Purchased on a "grey" market from other countries and illegally sold in the UK
  • Counterfeit products not produced by Alpine or Four’s distribution list.
  • Damaged, defective, or previously used products (called "B" stock products)
  • Products purchased or stolen from authorised dealers or other sources

Many times, the unauthorised dealers will attempt to remove or alter the serial number. In addition to being illegal, the removal, alteration, or tampering with the original serial number will automatically void the warranty on that product. unauthorised dealers may deceive consumers by implying the product is covered by proper warranty policy. Again, any products sold by unauthorised dealers are not entitled to warranty coverage. The legitimate UK distributors are using best efforts to prohibit companies from taking advantage of consumers, but these practices still exist. We recommend you to be very careful when selecting a dealer prior to making your purchase.


Our suppliers have taken a strong leadership role in the battle against unauthorised distribution:

Serial number tracking

Products are identified with a distinct serial number that is applied to individual unit boxes and the units themselves. All serial numbers are represented both alphanumerically as well as in UPC format.

Hidden Serial Numbers
Some products also have a separate serial number embedded internally in each unit. This will allow easier tracking and product verification.


Authorised dealers have been carefully selected based on their commitment to customer satisfaction and knowledge of mobile electronics.
Dealers have experienced sales and application staff trained to maximize the quality and value of the products they sell.
Dealers have been trained by Alpine Electronics and Four Masters in the application and integration of their products.
Authorised dealers have access to direct factory support from the team of experts at Alpine and Four including online and live telephone support as well as regularly published technical updates.
Authorised dealers offer full factory warranties on all products. Products purchased from unauthorised dealers or sources do not have a factory warranty.

Our suppliers fully support and encourage participation in the (MECP) Mobile Electronics Certification Program. MECP is a certification program for salespeople and installers, which tests and benchmarks individuals against the minimum industry standards of knowledge and practical skills.
Authorised dealers have signed a Dealer Agreement with Alpine and Four that allows sales only from approved locations and only to consumers. The resale of these products to unauthorised dealers is prohibited.
