While I appreciate soundman98's well intentioned reply, I find it hard to believe that an industry as technologically advanced as auto audio electronics cannot solve a seemingly simple problem.

AudioControl's main selling point - and the reason I was willing to pay a premium price for their product - is that their aftermarket products negate the necessity to replace the well integrated features of modern cars. It may well turn out that my options are either to reinstall the OEM factory speakers, amp, etc or to purchase a HU that will work with the aftermarket accessories I've purchased (and spent an inordinate amount of time learning how to install them correctly).

In the latter option, if something as simple as a non factory speaker can cause such problems to a high end sound system is there any reason to believe that similar issues would not arise from trying to integrate an aftermarket HU into the many features of modern steering wheels, phones, etc.?

Pardon my frustration but I think it is well founded. I find it hard to believe that this problem can't be solved.
