I've been using rockbox for a little while now, and I'm quite pleased with all the things it can do!
My recent dilemma is a bit puzzling for me though.
I recently bought and installed a Pioneer AVIC F90BT DVD/Nav system (Firmware 3.0 official) in my car. It's got compatability with everything, and one of the nice features is a line in right in the front face. Well, i've been using that for awhile to play back music from my iPod, and a lighter adapter to charge it. Now, the unit comes with an iPod dock connector cable to let it talk to/charge/get audio from the iPod. I thought, what the heck, i'll give it a shot, worst case i can get audio that way without having to run the stupid cable up to the front of the unit.
So, I installed the cable, (which uses RCAs for A/V, and a USB port for data comm) and proceeded to hook an Apple-firmware Nano up to it. Things worked fine, it played audio, showed album art, the whole nine yards. Then, I plugged in my RockBox iPod into it.
Well, nothing worked. RockBox went into sync mode (usb icon) and nothing happened. I unplugged it after a short bit, since the head unit wasn't able to talk to it. However, after unplugging, the USB icon on Rockbox did not go away. All keys were locked up. I did a reset on the unit, and when it rebooted, I got the "Please connect to your computer and use iTunes to restore" message. Well, that comes up once in a great while and a reboot usually solves it, so I rebooted a couple times, but kept getting that message.
So I took it back inside, hooked it to my computer, and it dropped into disk mode. Tried using Rockbox to install the bootloader again, but from what it was coming back with, the official firmware wasn't there, or was too damaged to install Rockbox to. So, i reformatted the iPod, reloaded rockbox, and tried it again, just to be sure it wasn't a fluke. Same thing happened.
So, after restoring it again, and then installing the stable version of rockbox.. (I was running the current build) I tried again. This time, as soon as I plugged in the dock cable from the head unit, the rockbox USB icon showed, then the iPod restarted into disk mode and the head unit told me it was not compatable. I tried plugging/unplugging a few times to make sure this behavior was consistent, and it was.
I also tried flipping the Car Adapter Mode between it's two settings, but that didn't do anything for me.
So while I know that serial comm isn't working well yet, and that there's no compatability between rockbox and most accessories, at the least I'd like to have some audio out, maybe even charging. This is more a word of warning to people so they don't get stuck with a corrupted firmware when they try and plug their player into their Pioneer unit.
Which brings me to my other question.. Is there a way to have Rockbox just not try to connect to the USB host? Even if the dock connector was just used to output audio and charge the iPod, that would be a ton better than what I have now, but whenever I plug it in, rockbox goes into USB sync mode and disables access to the menus. I could unplug the USB cord that hooks into the dock connector, but then I don't get charging.. which is where I might be headed.
Anyone else know of something I could do?
