First release. Shows the Android Auto map (Google Maps or Waze) on the VW digital cluster.

Supported: Harman MIB2.5 "Discover Pro" 9.2 inch, firmware MHI2_ER_VWG13_P4521 (shown as Software: 1367), with a digital cluster and Android Auto over USB. "Software: 1367" alone is not proof, because a second firmware shares that number. You do not have to work it out: the installer checks the real firmware and changes nothing if it is not supported. See Supported units.

Needs: nothing else. The MQB Coding MIB2 Toolbox is optional but recommended, with its SSH service, as a way back in if anything goes wrong.

Install

Download AAClusterMap_MHI2_v1.0.0.zip below. Do not use "Source code": it has no built programs. Then follow the Quick start. In short:

  1. Format an SD card as FAT32 and copy everything inside the zip to it, so AAClusterMap, Custom and metainfo2.txt are at the top level. Put it in SD slot 1, with the other slot empty.
  2. Engine running or a charger connected. Hold MENU for the service screen, then Software updates/versions > Update > the SD card > Android Auto Cluster Map.
  3. Hold the power button for ten seconds to reboot. Plug in the phone and switch the cluster to its map view.

The update checks the firmware, adds the NavActiveIgnore patch if it is missing, switches off the turn-by-turn arrows jar if it is loaded, and installs the cluster map. It also puts an AAClusterMap screen in the green engineering menu (hold MENU > Testmode > Green Developer Menu) with status, uninstall, logs and a switch to turn arrows. What it did is written to AAClusterMap/update_result.txt on the card.

If your firmware is not supported

Run the update anyway. It installs nothing and copies the few files a port needs into a porting_... folder on the card. Open an issue with your car, your firmware and the info.txt from that folder. Do not post the other files in it: they are Volkswagen and Harman software. See the support matrix.

Uninstall

Green menu > AAClusterMap > Uninstall and restore original state. Or move UNINSTALL.txt out of the folder to uninstall, move this file up one folder into AAClusterMap and run the update again. Both restore the original state.

Status

  • The cluster map, and the installer run over SSH, are tested on one car (VW Golf 7.5). Driving with a route works, and the map resumes after the phone is unplugged and plugged in again.
  • Installing as a software update, and the green menu screen, are new and have had little or no testing on cars. Reports are welcome either way.
  • Read Safety and recovery before installing.

Not included

  • Steering-wheel zoom of the cluster map. No working input exists.
  • Turn arrows together with the map. A menu entry switches to arrows instead.
