INTRODUCTION

Starting January 17, 2020 the first TomTom map update for Gen 4 Denso CP1 navigation equipped vehicles was made available. While the map update process is user friendly, we ask that retailers assist customers with the map update download, if requested, as a courtesy and an opportunity to build retailer loyalty, ensure customer retention and keep 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. Retailers are welcome to do this on their own. Retailers can use the site (dealer.subaru-maps.com) which is unique for retailers and not the same as what customers will be using at home. If the retailer service, sales, and/or parts managers do not have a login, please create an account from this page. You might have to wait for an approval email, once your retailer email has been approved.

MATERIALS REQUIRED

Windows PC or MAC
A valid e-mail address to register in website
Subaru VIN planning to update
USB 2.0 or 3.0 drive, at least 64GB in size (we recommend SanDisk®, Kingston®, Transcend® or Verbatim® brands)
