CarCanvas 1.0

CarCanvas 1.0

Overwrite CarPlay wallpaper caches with your own images.

Download

Attach and install CarCanvas-MobileHouseArrest.ipa from Assets below.

Install

1. Download the IPA
2. Sign it with an Enterprise / In-House certificate (e.g. ESign)
3. Install on device

App Store, personal certificates, and AltStore will not work. See the README for the full setup and overwrite flow.

A paired CarPlay system is needed first so wallpaper cache files exist to overwrite.

Quick flow

1. On CarPlay, select the 6 patterned wallpapers so caches are created
2. In CarCanvas, create a local CPBitmap
3. From History, overwrite Dark / Light cache files
4. Power off and restart the iPhone once

Notes

• Source code is not published; this release provides the IPA only.
• Use at your own risk. Behavior may break after iOS / CarPlay updates.

CarPlay の壁紙キャッシュを、自分の画像で上書きするための初回公開 IPA です。

導入

IPA をダウンロード → 企業証明で署名（ESign など）→ インストール。
App Store / 個人証明 / AltStore では使えません。詳細は README（日本語） を参照してください。

上書きするには、先に CarPlay で壁紙キャッシュを作成しておく必要があります。上書き後は iPhone の電源オフ再起動 が確実です。
