Fresh software for old head units

New apps almost never target Android 5.1 (API 22) anymore — yet that is exactly what the Geely Tugella head unit and other models running GMCustoms firmware ship with. Tuga ecosystem closes that gap: a self-hosted app catalog + 5 utilities, offline-first, with WiFi-based updates.

Installing on the head unit

  1. 1. Prepare a USB stick

    Format FAT32 (ExFAT is not readable). Capacity ≤ 32 GB — some head units don't recognize larger drives.

  2. 2. Download the ready-made USB bundle

    A single ZIP with all 6 APKs already in the correct folder layout. Unzip into the USB root — done.

    📦 Download tuga-bundle.zip

    Rebuilt daily from the latest releases. All versions and SHA-256.

    I'd rather assemble it manually from individual APKs

    Download APKs from the cards above (or each repo's Releases). Folder structure on the stick:

    <USB root>
├── TugaStore.apk            ← install first
└── apps/
    ├── tugasettings.apk     ← install second (creates ContentProvider)
    ├── tugaobd.apk
    ├── tugagps.apk
    ├── tugamedia.apk
    └── tugasync.apk

  3. 3. Install TugaStore

    Plug the stick into the head unit → open ApkInstaller / Root Explorer → tap TugaStore.apk → Install.

  4. 4. Install the rest via Tuga Store

    Open Tuga Store → App catalog → tap INSTALL on each utility. Tuga Settings first.

  5. 5. (optional) OTA updates over WiFi

    Starting with v0.4, Tuga Store will poll miktuga.ru/api/manifest.json and offer updates without USB. For now — USB only.

Why USB on first install? The head unit ships without Google Play, so the first install must be a sideload. After that, Tuga Store handles the rest automatically.
