Greetings everyone..A question has been aroused from my nephew about replacing his touch screen hu in his Volvo S40/2010 model, in which he took to a Local car Audio shop and was told that it would be very expensive and best just not do it till adaptable parts are readily available at a later time to save some $. I myself have done several installations in several vehicles, but never in a Volvo of late models per say.I have looked vaguely into the replacement of an after market unit in which seems to be very little information on installing/or an adaptation of the existing utilizing the unit in place.There is always the easiest solution of installing an after market within making it quite functional for all after market amps ect while keeping the existing unit in place and functional other than audio, in which is always the easiest route rather than chopping up and trying to utilize the existing functionality and having issues down the road as well as headaches to follow.Have any of you found or installed a fully functional touch screen unit for this vehicle?If so, what parts and steps have taken place?Ive been installing car audio for well over 15 years and it seems that the newer vehicles are becoming more and more of a PITA.Thanks, and Rant on if you will, and all information will be considered and appreciated as well
