Made with ease of use

Although, it's another added expense, this makes changing to an aftermarket stereo simple and you can keep most factory options.

Pac Audio for the win

We added a new headunit to a Ford F150 and this was perfect for the new radio to function properly and the factory chimes. Easy to install and great quality.
