Yea I know about it, even my 2005 the DIC display is part of the radio, to even install another head unit needs a $175 adapter from Metra. Not that installing audio is a piece of cake anymore, removing a motor is blood, sweat and tears kinda stuff. The window, I wouldn't bother, only bottom end cars nowadays don't have power windows unless it's like a classic Porsche or something that's worthwhile upgrading, why bother?..
		
		
	 
i have a truck with manual windows, i prefer it that way. my civic has manual windows as well, ill change them over to electric. when buying cars, some people see options differently. some will opt for manual windows to save money and allow them to upgrade something else. 
finding the right ignition source can be the trickiest part of stereo installation these days. as the adapters have made that part pretty easy. same with alarm installation, which i think is definitely an art form. especially finding creative ways to tuck and hide them, to make them much harder to disable. 
	
		
	
	
		
		
			Wiring isn't a big deal either for a EE minded person with the proper tools.

Nothing in a car is really hard when it comes down to it, just time consuming.
		
 
		
	 
some people dont think like an EE, myself included. i actually make decisions. :biggrin:
im a programmer that does graphic interfaces, so im pretty detail-oriented as it is. i dont have many problems with wiring, since i do control wiring for industrial controllers. not everyone has that kind of background, thats why they go to specialists. its also why my friends shop makes decent money selling stereos to people that want to try to install themselves, only to bring it all back and ask for help fixing what they bunged up.
