Old phone replaces car head unit with Android Auto
1 min read
Headunit Revived lets an old phone act as an Android Auto receiver, replacing a costly head unit. The free app uses Wi-Fi Direct and a Wireless Helper app for wireless connection. Audio can route through the main phone's Bluetooth to car speakers. The setup avoids the $200, $600 cost and installation hassle of a replacement head unit.
