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. ..."

- this accessory supports charging for the iPhone 3G, iPod touch (Gen 2) and iPod nano (Gen4) with most iPod docking stations
- Snaps into any iPod universal dock and accepts universal dock adapters

same here, so you're not alone.

i have somewhat of a similar problem with my ipod Touch and my JBL docking station alarm clock thingy. It may just be that the ipod is not compatible on some of the levels that the Igroove is. With my docking station, it wont charge my ipod touch itll only play music

i tried it again and it didnt work so i went back to argos and got another one and it worked then it was my 1st ipod it was faulty lol

Yes, the docking station is damaging the iPod. The vibration when used load is causing damage to the iPod. If you notice, the iPod will only freeze when it is playing load in the docking station. To avoid the problem, you'll need to play the music at a lower sound with less vibration. Once I began to play my music at more reasonable sound levels, I discontinued the problem. Very disappointing solution...but it is the answer. I too called Altec Lansing. They are not aware of this issue...I told them to search the internet - it's all out there.

hy altec lansing have big problem whit her power supply block so change it first bey and good lock

I called Altec Lansing technical support (1-800-258-3288) and stated the problem with the 4th generation nanos not charging. The man I spoke with was aware of the problem and will ship a new unit to anyone calling in with the same issue. I am required to send my unit back to them and they will ship a new unit with a different pin configuration that will solve the problem. You are required to ship the unit with proof of purchase (copy of receipt) to the address they provide in Milford, PA. You will only be out the shipping charges to get it there. He mentioned that I should receive a new unit (Not Rebuilt) around 10 days after they receive mine.
