I have bought 4 Digital TV systems and 2 Audio systems over the past 7 years to install in my Nissan X Trail ST-X 2004 model. They varied in screen sizes from 4inches to 8 inches (I had to cut face plate to install it in the DINS) however, non seems to provide me with satisfaction until I bought 'G2213D Eonon 7" Digital Screen DVB-T Car GPS DVD Player Double 2din Stereo' two months ago for a total price of $284 without Australia GPS maps as I was not prepared to spend extra $100 for the maps (I had alternative plans to get maps). I had also experimented with many types of antennas for use in car including normal tv antennas with built-in-boosters. Non seemed satisfy me.
It is a totally different experience with EONON. I removed my NISSAN factory assembled stereo system and used EONON as it has a 60Wx4 amplifier and amazingly, everything is to my satisfaction now. It has the best DVB-T receiver with the best antenna (you get an antenna) and everything including bluetooth phone connection is to delight.
DVB-T - 7 inch
Stereo Radio Tuner
Reverse Camera input
Many Auxiliary inputs (audio and video)
2 SD card slot (for media as well as for GPS maps)
This is fantastic. I am never going to shop for anything else. I now have to replace my face plate in my NISSAN as I have cut it previously to install 8 inch LCD.
