adding iPod trigger lead?

Ok guys, I have done a search here on the boards and returned nada that was relevant. I have also done hours of research on the net and found nothing. I called PIE and Soundgate, where I didnt get any assistance. I think I might have our first stumper of the day :) Car: 2000 Lexus SC400 Objective: Adding iPOD source to stock amplified Lexus system with autoswitching. (not inline switch) Details: I already got ahold of PIE MPSS-2 autoswitching relay. http://www.logjamelectronics.com/piempss2.html After scouring the installation, it became clear that although this unit could work w/ 1 trigger, it would not work in my situation b/c it would turn off the stock amps. Thus, I need 1 trigger for Lexus HU (equipped) and 1 trigger for the iPOD? How can you install a trigger on a MP3 device? I looked at low-voltage trigger boxes (PIE 1VT), but the device doesnt have the current. Next, I even found from SoundGate a 12 Volt Speaker Trigger http://www.soundgate.com/index.php?request=product.details&categoryid=25&productid=368&usereferrer=1 Where I called them and they said the iPOD doesnt have the current. Everyone knows that the trigger lead is a simple 12+ wire that turns on with the unit and off with the unit. There has to be a way of installing this without a 4PT switch. Is anyone proficient enough to solve this scenerio and still obtain the main objective?

Can you not run a relay(s) that will power up the amplifier regardless of the switching ? Have a relay that will interupt the remote turn on lead or the wire that is controlled by the switiching unit and have it separate from the switcher so that it doesn't get affected by the triggering device ?Jeff

Nakamichi System Im sorry, I should have posted that the system was a Nakamichi Premium and not the normal Pioneer. Ideally, the setup imagined was that when the iPOD was turned on, the headunit source would automatically select the iPOD; not turn off, where the HU would "think" it was still playing. I was going to intercept the leads after the HU and before the amp to "hijack" the system. After the iPOD was turned off or removed, then the relay would switch back to the playing HU. Thus never having to touch the HU. It would be all automatic. Jeff, you proposition could work. You would just have to turn the HU off, then play the iPOD source. When you were done, then turn it back on. The wiring for the Nakamichi is complicated, where although I have the Lexus diagrams, I am not sure what signals fron the HU the factory amps need inorder to play. What do you think?
