Wanting to swap 03 grand marquis OEM radio with OEM radio from 03 Focus, part# 3s4t-18c869-ag... is this possible and if so how difficult?
Not sure are the part numbers the same? Also do you have steering wheel controls? they may not be compatible on that front. I would see if you can get pics of the back to see if the harnesses match too.
