Dennis, Thanks for asking, here are my thoughts
1. I am open to replacing the OEM HU, but need to understand if the OBC will still work. My car is equipped with the OE DSP and hence Dynavin and Eonon cannot be fit
2. I need to use the steering wheel controls
3. Can also replace the Amps and Speakers and add on a sub as well
The most critical factor is that I would not have any expert advise other than on this forum regarding what parts to buy, where from, and on installation. If I have this, this I would not mind going for it.
The other factor is that it should not look awkward as add ons and still be tasteful and fit well.
Would appreciate any thoughts in this direction.
