Hi everyone,

Just joined the forum and just received and installed my 4500BT yesterday, I ordered the CDIU201S but that won't arrive until mid October. I have a CDIU50V cable that hooks up to the USB port in the back and the aux in port. I have full iPod and iPhone functionality, however the apps option is greyed out. I downloaded the app radio app on my iPod touch 4th Gen and it seems as though its connected, I would then hit the app mode option on the pioneer deck but its mirroring and I am not able to touch or swipe anything. Basically I can see the app menu option but not really through the app option on the x4500bt. Any ideas, suggestion? Micro bypass installed as well.

I have the same one but haven't bought the cable yet. I thought you needed the CDI cable to use apps? Also there's a way to mirror your iPhone/iPod screen but not sure how to make it work with this particular model.

Info on what is required for your unit and App Mode can be found at the Pioneer web site.

you need the app mode cable I basically want to be able to mirror whats on my phone and be able to use any app I want the newer model of this which is the avh x4600 bt just makes things even more complicated 

I have the exact same problem and i have all required cables (pioneer CD-IV202AV) but I'm still not able to get advanced appradio on my x4500bt! All it does is mirror whats on my phone. Can not control iPhone from head unit.
