i just picked up a PAC SWI-PS from ebay for 45 bucks, the next thing is should i get a PAC os-bose or a Metra GMOS-04. what are the pros and cons of each. thanks. also how hard is it to install the D3 into my 2005 GMC. i really dont want to pay 300+ for install, but then again i dont want to jack up my install doing it myself.
thanks
