Audio Systems/In dash navigation system


I have a 2003 Chevy Impala that I am looking to install an in dash navigation system. The system I am looking for has an am/fm receiver, GPS and Cd/DVD player. My question is will the message center alerts still be accessed through the new system.  For example, if my tire pressure is low, I get a message. When I correct the problem, I use the stereo to reset/clear the message. My current stereo also is where my car alarm is set. How do the things work if a different stereo system is installed?

Functions that are incorporated into the factory headunit will not work if you put an after market headunit in the vehicle.
That said, you might talk to the folks at about what your options are. You may be able to interface through the CD changer input for the factory system or through an FM modulator but they would be the people to discuss things with when you want to interface to an existing factory system.

My forte is audio.. Car/Home/Boat. You name it, I will help you even if it is just a link to more assistance. If you want to interface new gear to your factory radio I can do us both a favor and tell you to go to or call them at 1.800.555.7088. They really are top notch at doing that for people with great support. I will re-direct most questions of that nature to them. The rest of it... I am eager to help you with. I am also not a 'Master Installation Technician' that will tell you I cannot assist you with cars not made in the USA. Talk to me about any audio upgrades including 'bang for the buck'.
Specialties include: Overall Acoustics, Gain structure/settings and Enclosure design, system design/consultation, when/where to get which upgrades as well as other pertinent info for the mobile audio enthusiast and much more.
I also am NOT interested in buying your used gear so do not waste our time asking me.
