There are a few things to be considered before getting a double DIN head unit. First of all the technology. Make sure the head unit you are getting is included with the modern technology like: Bluetooth, hands free calling, audio steaming, USB/AM/FM available. Also the audio quality the head unit provide must be high quality so that the speakers can perform well. Also make sure your stereo system is allowed GPS, high quality video and lot more.
I like the service of Pioneer more than any other. It is one of the best brand that provides you with large number of head units, and other products that are made especially for making your car the best than any other’s.
The review is really helpful. Thanks for sharing.
