I have checked this unit can fit your car.
1.If it is Optical Fiber Amplifier, then need to replace your current (existing) Amplifier system. And this unit has built-in amplifier.
2.Yes, this unit has built in Amp. And it will have good sounds.
3.Yes, it is just plug and play. But if your car has Optical Fiber Amplifier, we will send you a 6m long power cable to connect speakers directly under the boot(under the spare tire or on the left tire). Also don't need to cut wires. But need to connect speakers.
4.No, this unit has its own clock which is got from satellite navigation. When this unit power on, the satellite navigation will locate, and the time will update. The original radio unit will be removed when install this unit.
