I just finished installing the Vais SLX and XM Direct tuner. (Thanks to BobR for telling me about the Vais unit. The radio sounds great, and I've got 16 character display!) When I first started the car after the install, the red triangle appeared. I shut it off and restarted it with the same result. A quick check of the ScanGauge showed no codes. I spent no time with further troubleshooting due to the late hour and chilly temperature. For the install, as part of removing the dash piece with the Park button I disconnected an electrical connector on its back side. I assume the wiring for that connector runs to the Park button. I will check that connection tomorrow to make sure I reconnected it securely. The only other connectors I deliberately messed with were for the radio. Any other theories as to what might have happened? Thanks in advance for any assistance.
