On post-install testing everything worked fine. But when I got back in the car this morning the head unit failed to find the SC1/Sportster. When the head unit powered up the channel preset list appeared momentarily but with no channel info text. Then the head unit turned itself off.
When I turned the head unit back on, pressing the SAT/AM button wouldn't call up the SC1/Sportster--I could only get AM stations. I turned off the car's power, then turned it back on and could then press the SAT/AM button to use the Sirius radio again. There's a loud pop every time the Sirius radio powers up, but everything works again--presets, tuning, audio output, etc.
After some troubleshooting I noticed that the failure is related to the smartkey system. As long as the key fob is in or near the car I can turn the car on and off and every time the satellite radio functions normally--though the pop is always there on startup. If I take the key fob away from the car, then come back and turn the car on, I get the failure noted above.
Anyone seen this before? Any ideas for resolving the issue? Seems quite strange that the smartkey would have an effect here. And is the pop on power-up normal, or is there a way to fix that, too?
I assume this is Push Button smart key technology. Try This:
Press the start button once(without the brake pedal) to activate ACC mode
Next Press the brake pedal and then press the Start button.
For some reason several people I talk to have had problems with push button start and this has taken care of it every time. It is an extra step you have to take, but no one seemed to mind it much.
The Power-up POP noise I have seen resolved in the past with a noise filter. A few large amplifier car audio systems I have worked on suffered from this and a noise filter was the solution. It would have to be wired into the power system of the vehicle.
The key fob thing I cant understand, So when you get in the car and start it is works? But when you leave with the fob and come back it does not work? When you come back with the fob try and just hit the start button(without brake pedal) then start button with brake pedal to start the car.
Post back any results from this or if I am unclear on something, Thanks
