IPod Touch 4th Gen will dock. Will Charge. Can use remote control to play, and shuffle songs from iPod, but sounds will not come through speakers on Philips SBD8100 Speaker Dock for iPod and iPhone

It is, but you need to have the AC adapter plugged into it for it to work.

ipod touch has a light piece of plastic on bottom where it connects to the dock youtube has a video on how to remove it softly with a razor blade and once it is removed it will work properly although to be played through stereo i must have my ipod touch 4th gen on airplane mode

Hi, while your pure express plus you just purchased is not playing out any sound is because, the speaker that enable you to play the sound when you play music through the ipod is faulty and it needs to be replaced with another one for it to function properly again.

After changing the speaker that is faulty with a new speaker, you can now start enjoying the music again through the internal speaker.

Take care.

Maybe this could be the solution...

Important Note: iPods released since Sept 2008 (e.g. Touch 2nd Gen, 4th Gen iPod Nano and iPod Classic 120 Gigabyte, iPhone 3g and onwards) have an updated dock connector that means older revisions of speaker dock may not be able to charge these newer models of iPod/iPhone. Older docks should play music from these newer models with no problem.
The problem with charging is due to Apple removing support for 12v (firewire) charging on these new models of iPod/iPhone. Only 5v (USB) charging is supported on these new models. ..."

WHEN CONNECTED TO PC IT DISPLAYS OK TO DISCONNECT

You need to reset your ipod. You can go online to find out how to do this. I had to do it with mine and then it worked perfectly.

yes just eject it from the computer and it will keep charging and if you have on that plugs into the wall then just unlock it and click the center button!!!!

not likely the new 4 gen Ipod has different pin set within its dock connector system for the video output which has made many 3rd party accessories no longer able to charge the ipod but it will still play music
