=== Steering Wheel Controls ===

On GLL models, steering wheel controls were available for basic head unit functions, including:

* Power on/off
* Tape selector
* Tuner band
* Scan
* Volume control wheel

These controls operate using an LED built into both the steering wheel and steering column. The sending unit (in the wheel) transmits a signal to the receiver unit in the column. This receiver then relays the signal wirelessly to a separate receiver box, typically located under the rear compartment (2-seater) or rear seats (2+2).

Note: Removal of the receiver box will disable cruise control functionality. Most aftermarket head units can use the steering wheel controls with an adapter such as the PAC SWI-X converter.
