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.
