mikeinnj Posted November 14, 2008 Report Share Posted November 14, 2008 So, my last complaint with the F series has been that it has been dropping my iPod constantly on bootup about half the time. I got my F700BT a few days before Halloween. My iPod didn't drop once until the 4th day or so. Then it dropped continuously atleast once every day upon bootup. For the past two days, I have gotten in and out of my car about 10 times a day and the iPod was picked up EVERY SINGLE TIME. I also noticed something else... I noticed that I have not had my SD card in the unit either. I also did not start leaving my SD card in the unit until about 4 days after I got the unit. So, for me anyway, taking out the SD card has totally fixed my iPod problems. And to double check this, I put the SD card back in, booted it up and sure enough, the iPod was dropped by the 3rd bootup trial. My theory is that the problem lies within initialization of all the sources on bootup. From what I can tell, the order of when the SD and iPod get initialized affects how the system sees the sources. The SD card reader in the unit probably runs off of the internal USB controller, much like the SD reader in my home computer. After all, the AVIC is just a Windows CE computer. So, if the SD reader is running off of the internal USB controller AND as we know the iPod also runs off of the USB controller of the unit, therein lies the problem. The initialization of the SD as a source on bootup is screwing up the timing of the control commands sent out to the iPod. So if anyone else has a recurring issue with the iPod not being recognized on bootup, try removing your SD card and see what that does. It does make sense though that it would be a problem with the timing of the USB initialization since every time the iPod drops, it works again right away when you unhook the reconnect the USB cable. That's my theory anyway. Quote Link to post Share on other sites
k87 Posted November 14, 2008 Report Share Posted November 14, 2008 you could be right...i have an 8 gb sdhc card that i keep in my car but do not keep in the unit...i never have a problem with my ipod dropping..in fact it only happened one time in october (i remember it vividly cuz i was driving lol). So for me it very rarely happens (it has yet to happen with the new update), so i would say this could be the cause because when it did happen to me my sd card was in the unit. My unit is also the F700. then again you could be wrong...as im sure a couple people on here will tell you because they "have their sd cards out and it still happens"...we shall see.

dan2010 Posted November 14, 2008 Report Share Posted November 14, 2008 Since I've taken out my SD card I've noticed two things, my ipod connects everytime and button press for VR works reliably as well. Quote Link to post Share on other sites

t1m1t Posted November 15, 2008 Report Share Posted November 15, 2008 wut if i leave the fake sd card that came with the unit? Quote Link to post Share on other sites
terron Posted November 15, 2008 Report Share Posted November 15, 2008 wut if i leave the fake sd card that came with the unit? Since it doesn't have any electronics in it, it shouldn't make any difference. You should try it both ways and see if either one shows more promise than the others; let us know Quote Link to post Share on other sites
ckelly33 Posted November 15, 2008 Report Share Posted November 15, 2008 I don't have one of these YET...Does removing the SD card lose any function? I wondered if anything important was contained on the SD card, like the map, etc. Quote Link to post Share on other sites

I wondered if anything important was contained on the SD card, like the map, etc. nope, the unit is entirely self sufficient without any USB/CD/DVD/SD/LOL inserted Quote Link to post Share on other sites

That's my theory anyway. I have to give you a HUGE thank you on this one. You are 100 percent CORRECT about this. IT WAS THE SD card keeping the IPOD from being recocgnized at bootup. I called PIONEER and told them about it, and the guy was like oh no that was fixed in the 2.0 update. It wasn't. They are aware now that they still have an issue. Again, thank you, you solved my problem or at least gave me a workaround. Quote Link to post Share on other sites
NickyD32 Posted November 17, 2008 Report Share Posted November 17, 2008 not true. i never used an SD card and my ipod still dropped at least once a day. after the second update, no more drops... and i can't see how the SD and ipod are linked whatsoever. it makes no sense.

No, I don't mean the "iPod is not recognized" message that came up. Thats a different issue that has been resolved. I'm talking about the iPod just straight up dropping on boot. The SD and iPods are both running off of an internal bus controller on the Avic. That is how they are linked. Basic computer HW knowledge here. Quote Link to post Share on other sites
