Default SYS msg after stero installation...need some held

You guys continue to help me along with stuff, so I got a new one which someone may have experienced, which may have an easy or an expensive fix. Had the Bose pulled from the C4 today, replaced unit and speakers. We wired it so that the antenna doesn't come up without the radio being utilized. Car seemed to run fine. Drove it to the wife's retirement party today. On the way, I'm getting a SYS flash. I thinking, ok what did we do. It's saturday night, sunday nobody's open, monday is a holiday, and I wanted to drive the C4 up t Gillitte on Tuesday. Open road cruising kinda thing. CB and radar detector at full alert. Don't have an electronic code reader, so I'm thinking after checking the manual, just WTF is going on. My thoughts are that the computer system sensed a new add-on, and that getting rid of the SYS flash maybe as easy as just disconnecting and reconnecting the battery, to let the electrical system reset itself. Am I wrong, is there something else I should do, or should I take my daily driver on the trip and wait to get the C4 into a dealer upon return? Additional question, and boy am I ever dumb and torqued at the same time. During the installation, took off the information plate on the message information counsol and identifed that both the low/flat tire and service ride control lights were lite, but had black electircal tape over them to hide the lights being on. I've driven this car for four years with no problems, and ask this question, is it safe to drive drive and what is the fix to these problems. do I have additional ammunition to not drive the car to Gillette? Looking for any help anybody can provide....C4

You need to read the C4 Audio FAQ. It can be found under Audio/Electronics.

It has a link inside that explains the fix.

It's pretty easy if you used factory wiring.

If you were "stupid" like me and brought it to a professional who A. Didn't know about the issue and B. Ran his own wires from some random location, you might have a few more problems.

If "SYS" is displayed in the LCD section of the instrument panel cluster after installing a new stereo, do the following:

1. Buy (2) 1 kilo-ohm 1/2 Watt resistors. [Radio Shack part # 271-023. They sell them as a 2-pack for 29 cents.]
2. Disconnect the negative battery cable.
3. Remove the receiver.
4. Connect one end of both resistors to ignition power. (Yellow wire in the car.)
5. Connect the other end of one resistor to the purple/white wire in the car.
6. Connect the other end of the second resistor to the grey/black wire in the car.
7. Cover all connections and completely cover the resistors.
8. Reconnect the negative battery cable.
