Map Data Update Procedure for Harman Gen 3.0
Navigation Equipped Head Units (H/U)

INTRODUCTION:
On August 23rd, 2018, the first TomTom map update for Gen 3.0 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.
Materials Required:
1. A PC or MAC computer / laptop
2. A valid e-mail address
3. USB 2.0 or 3.0 drive, at least 16GB in size (recommended device brands: SanDisk®, Kingston®,
Transcend® or Verbatim®)
4. TSB 15-211-17R for reference.
SERVICE PROCEDURE / INFORMATION:
CAUTION: NEVER attempt to install this software update on any 2019 or 2020 MY vehicles as
they are equipped with Gen 3.1 Navigation systems. This update is ONLY for models equipped with
Gen 3.0 Navigation systems. Should an attempt be made to install any of these files into a Gen 3.1
H/U, the USB Authentication error screen below will be displayed.

CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.

trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

during the update process.
Never idle the vehicle in a closed space such as a garage, even if the garage door is open.
Once the vehicle is in a safe location, be sure the vehicle is in Park if CVT or Neutral if MT
and the parking brake is fully engaged.
Unplug any cables or devices from the USB ports.
