INTRODUCTION:
On December 14th, 2018, the first TomTom map update for Gen 3.1 Harman navigation equipped vehicles was made available. While the map update process is user-friendly, we ask that retailers assist customers with the map update procedure when requested as a courtesy, an opportunity to build retailer loyalty, enhance customer satisfaction and in keeping with the Love Promise. Retailers may also want to install this map update on any certified pre-owned or pre-owned vehicles in their inventory on their own. The site (dealer.subaru-maps.com) which is unique for retailers, is not the same as what customers will be accessing at home. If Service, Sales, and/or Parts Managers do not have a login, create an account from this page. There may be a short delay while retailer approval is pending.
