I had an Alpine CD player installed, and my SYS light started flashing periodically. I was told that it did that because there is a wire that is the LED power supply for the OEM head unit, that is not used when installing the aftermarket head unit. Is this installed incorrectly, or is this the truth and something I will have to deal with?

Thanks

There is truth to this. There is a TSB that covers what to do when you install an aftermarket radio. This is the TSB: http://www.corvetteforum.net/c4/dave8476/index4.shtml .
e-mail me if you have any questions about how to do this.

a bit easier to follow:

If "SYS" is displayed in the LCD section of the instrument panel cluster after the customer installs a new stereo, he will need to 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.


Good Luck!

Thanks guys.

Marcho Polo is right on. Just had the resistors put in last week, after a year of the SYS light.

SO, that's why my SYS light flashed the day I got the stereo back in 1998! LOL it's been so long, I never was too bothered by it. Time to fix it though...

Thanks!!!
