still need any help?

Maestro should have there own fit guide, It would tell you what it would retain and what it won't. etc. steering wheel controls, back up cam, sync, safety features. Some cars and certain radios it will show tire pressure, gauges and ac controls. Also it should retain the amp. How are you going...
