Toyota Vehicles With a Heigh10 Radio: Audio and Steering Wheel Controls Don't Work

If you have both issues, the radio and PAC data interface connectors might be swapped. On the PAC interface, find the Radio Harness connector, labeled at the bottom. It should have no RCA jacks. If RCA jacks are present, the harnesses are mixed up.

Applicable part numbers: RB10RUN10, RB10TAC16B, RB10TUN14, STH10HIGH18

This is an example of the wrong connector used in the PAC interface.

This is the radio's AV Connector where the above harness should be connected.
