marceltj4.6is Posted February 13, 2010 Report Share Posted February 13, 2010 Hi Everyone, Just got my unit installed with SWI-PS for the steering wheel controls. When I turn the car on the unit begins to boot. I hear audio start on one source and then 1-2 seconds later it switches to another. Usually AM and an all static station! I've been searching on here but can't seem to find any post with a similar issue. Does anyone know what this may be? Thanks! Quote Link to post Share on other sites
VBLUE42 Posted February 13, 2010 Report Share Posted February 13, 2010 See if you can unplug the SWI-PS and restart the unit. If the problem goes away you may have a voltage issue with the SWI-PS. Quote Link to post Share on other sites
dawgbone Posted February 13, 2010 Report Share Posted February 13, 2010 What vehicle? I know it can be an issue with some BMW's... Quote Link to post Share on other sites
fe342185 Posted February 14, 2010 Report Share Posted February 14, 2010 I have the same issue in my BMW X5. I added a resistor yesterday in line to the single signal wire and it did not fix that issue. Although I did have an issue with the horm pressing the band the button and that was fixed with the resistor. Quote Link to post Share on other sites

NFrazier Posted February 16, 2010 Report Share Posted February 16, 2010 Well I know that sometimes my sources change. But I know why. For instance, I have Sirius and if that's playing during bootup it sometimes switches to my iPod. This is the reason: My iPod shut off completely so when I start the AVIC unit it powers the iPod back up. The AVIC automatically switches to the newly "connected" source. Don't know why yours is switching to AM unless whatever source your on is getting disconnected mid boot-up somehow. Quote Link to post Share on other sites

That is not normal for an iPod to do that unless the battery is toast. Remove the iPod from the chain and see if the unit still switches sources when you power it up.

VBLUE42 Posted March 2, 2010 Report Share Posted March 2, 2010 Well what I am trying to tell you is that the iPod is not suppose to do that. It will only do that if the battery is dying and it causes the iPod to completely power off while the car is idle. The iPod never actually turns off. It only goes into a deep sleep mode.

fdisker2000 Posted March 3, 2010 Report Share Posted March 3, 2010 My Z110BT switches to ipod on starup also. Not every time but probably 7 out of 10 times (only when ipod is connected). Very annoying. Is there anyway to fix this? It is not because the battery went dead, because I have checked and it is fully charged. Quote Link to post Share on other sites
