Alex, most late model vehicles do not have inputs to feed an mp3 audio signal to your factory stereo. You would have to install bluetooth transmitter. A bluetooth transmitter will allow you to connect any bluetooth device to your factory radio. This is the easiest and most cost effective to add an audio input into your factory stereo. Here is the bluetooth transmitter you will need:

My 2004 Lincoln Navigator radio will stop playing without warning. Then without warning (usually in a day or two) it comes back on. Any ideas on what the heck is the problem? Anyone?
I have a 2004 Lincoln Navigator, I want to add a power line to feed my amp, where would be the best place to add a positive line, do I need to drill a hole? And where would be the safest place if so. thanks.
Arthur, most vehicles have a factory hole with a rubber or plastic grommet at the firewall. This is usually the standard place to run a power wire through the firewall. If one of these holes are not available or not large enough, a hole will have to be drilled to accommodate your power wire. Choose something on the engine side of the firewall as reference and try to match it up on the interior side of the firewall. This will make sure you do not drill through anything important. Then drill a hole somewhere near or beside your reference point. Make sure to use a firewall grommet to prevent the power wire from chaffing on the firewall that could potentially cause a short. Hope this helps. Good luck with your 2004 Lincoln Navigator amplifier installation.
