Hey all,

I have a 2004, Acura TSX (love this car by the way), w/Navi 6 CD changer. I recently had the iSimple ISIM74 installed into the Aux port into my navi. The ISIM74 outbound connects to my siriusxm (Onyx Plus) radio as well as a 30pin ipod/iphone connection.

When on SiriusXM, the AUX station is set to CD8 on the display. If I want to go to the 30pin connection, I flip over to CD7.

Here's the problem. I'll be listening to Sirius, and for no reason, the Navi switches from CD8 to CD7. There is nothing connected to the 30 pin connector when this happens. No rhyme or reason to when it changes. But it happens on a random basis.

I can't figure out why this is happening, but more importantly, how do I get this to stop?

Thanks so much!
