That sucks! I purposefully ordered the base stereo knowing I would upgrade; so many issues with factory “upgrades” dealing with Bose in German cars is an absolute joke; it’s gut everything or suffer.
Ya
That seriously sucks. When we ordered ours I purposefully got the basic sounds system knowing we would upgrade; the “upgraded” factory options just fall short and create a lot of install issues. Like Bose in German cars-



speaking of that- keep an eye on NAV-TV products; I had emailed them last year asking if they were making a Zen processor for the Kia, they may have it by now - they aren’t cheap but it’s the ONLY way I will do an install in a Porsche; it is a wicked high quality (errr and high cost) interface.
We have tried the idatalink with mixed results.
I agree - always hate the idea of loosing factory volume control, it’s a clunky workaround that you shouldn’t have to do

Keep me posted-
