APPLICABILITY:

2020MY Legacy and Outback with
Gen 4 Denso CP1 system

NUMBER: 15-268-20

SUBJECT:

USB Map Data Update Procedure for Denso
Gen 4 Navigation Equipped System

DATE: 07/27/20

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)

SERVICE PROCEDURE / INFORMATION:
NOTE: Gen 4 map installation is independent of any software update. Unlike Gen 3/Gen 3.1 Harman
map updates, there is no software installation as part of the Gen 4 map updates.
