Hello Apj,
welcome aboard ... short info in advance: whenever you ask for specific
help for your car, don't let the community guess about model, year built and equipment features.
I'd recommend that you'd rather arrange yourself with the given steering wheel and radio, as an upgrade will be way too expensive because of the involved parts ...
as there are:
- radio (depending on model/brand)
- multi function steering wheel + control unit
- air bag (!!)
- return ring with slip ring for radio control
- wiring attachment to the radio
- programming (air bag and radio)
Anyway, enjoy your new car ...
