• The application is available for under $4 on Google Play or free via GitHub, offering an alternative to costly car head unit replacements.[Engadget]
• Testing showed setup required configuration experimentation, while Bluetooth connections introduced audio latency mitigated by wired auxiliary cables.[Engadget]
• Performance on genuinely older tablets remains unverified after tested older devices failed before testing could occur.[Engadget]

Key facts

• The Open Headunit app costs just under $4 on Google Play and is accessible for free on GitHub.[Engadget]
