The purpose of this research is to build the electronic map service quality index for users on automobile satellite navigator of the market. This research is done by interviewing dozens of scholars, experts in geography, measurement and persons who edit and design the electronic maps. We investigated about eight scholars, analyzed and summed up all from this interview, and then adopted Analytic Hierarchy Process (AHP) to make the electronic map service quality index of the automobile satellite navigator. From this 20 scholars and 30 users of the analyses and results, we infer how the electronic map of automobile satellite navigator can be applied in design in the future to satisfy the consumers? demand by offering them sufficient road and geographical information, in order to promote the satisfaction level in using the electronic map. From the above mentioned analyses, we can construct finally a standard on the electronic map service quality of the automobile satellite navigator and as a result, we obtained a valuable proposal and index to improve the service quality according to different levels and percentage. In addition, we offer to the manufacturer variant service aspects in different service levels, and therefore, from the analyzed result and suggestions, we expect to provide the reference information of improvement and studying for the manufacturers who produce electronic maps and the agencies who sell the productions of automobile satellite navigator.
