Aftermarket stereo and DSP. No sound problem.

[NickUA]

Hi to everyone! I’m new here. Own 2005 4.8is DINAN. Trying to install this radio https://www.seicane.com/android-car-...wifi-sia-s6902 and meet no sound problem. Car has DSP and factory NAV. I know that I’m not alone with this problem and there where topics like my, but there is to much information to search. If somebody point me where to go or better what to do I would be very happy. I’ve read topic here on Xoutpost about this radio ( more than 100 pages but still didn’t find what to do. I’ve visit couple local car stereo shops and they told me that this radio will not work with DSP and I have to rewire everything and bypass DSP which I don’t won’t to do. So all you guys are my last station! If no I’ll have to sell radio and forget about it because to rewire and bypass everything is to expensive. So I hope somebody will help me. Thanks and cheers to everyone!
