Hi , just installed Erisin Android Headunit of eBay and there are a few issues with it.
The first and the major one is the Sound quality its real S*IT compared to the original headunit . I can head a cracking noise with the volume up and there is a lack of bass too. Same as this video https://www.youtube.com/watch?v=6urdtJ2eM3M
The 2nd one is that the buttons stay constantly illuminated
And the 3rd last one is that the aerial connector on the back seems to be too big and the unit wont fit flush because of it touching the plastic behind.
