I think the answer is no, adding these items on the production line is relatively simple. The wiring for all options is always installed, just a matter of what speakers are fitted, amp, head unit etc. Adding these items afterwards would be possible but more expensive and labour intensive.

I'm going to add some aftermarket items and try my luck. If you're leasing then try something like a Blaupunkt Velocity V2Go. I know, "what the hell is that?" you say. Google it. No permanent install required just power and an audio signal.
