Sir freeloader, I am getting an error when replying through PM, so I will just post it here. The Sony XAV-650BT cost 12k from the Aaron Samuel store in Banawe. It needs a Sony Steering wheel control adapter that cost 1k to make it work. Then an additional 300 for the antenna cable for AM/FM listening. The rear camera costs 1.5k from the same store, and I am very happy with it's performance.

The reason why I chose this compared to the Pioneer X2850BT is to try out a different brand. I am already using an X8850BT in my CRV. Tuning wise, I think the X2850BT has more because it has time alignment. Sony is limited to a 5-band EQ, Crossover adjustments, Fader/Balance. I think that's it. The key selling point of this Sony is the rotary volume knob. I like those more than pressing butttons on the HU to quickly adjust the volume.
