Can someone tell me what is involved in retrofitting a stock Navi into a 04 sedan that did not come with one? How much do they run and what kind on installation issues do I have to deal with? I love the Navi system but got such an awsome deal ($5600 off MSRP).

 

Get way more for your money and get an aftermarket navi/HU like the Eclipse/Kenwood/Pioneer units. Way better sound and touch screen.
