4th Gen Nano not charging with speakers or FM transmitter

Firewire-compatible iPods accept charge on a 5V connection (used by USB) and a 12V connection (used by Firewire). While Apple has supposedly been warning accessory manufacturers for some time not to rely solely upon the 12V connections, this advice has not been heeded universally. As a result, as Firewire gets phased out of the iPod line, those accessories which deliver a charge only on the 12V connectors cease to provide power. This has been a complaint with 3G iPhone users as well, as the 3G iPhone also no longer supports Firewire.

From what I can tell, this sounds more like short sightedness on the part of the accessory manufacturers more than anything else. Granted, as car electrical systems run on 12 volts, it's logical/easier to just use that without having to do the conversion down to 5V power. Long story made short, it's an awkward place to be in as a consumer, as seems to be the norm when it comes to power and power adapters.

You're right, this is rediculous. I bought a Bose sound dock a couple of months ago, £250 ($450). This week I bought the new 4th Generation Nano, and it doesn't charge in the dock. Not sure what is the waste of money, the Bose or Nano!

i have the same prob. different sets of speakers do not recharge the nano

Are there any adapters in work to fix this issue? I would hate to buy a speaker set that won't charge. I miss not being able to charge in my car with my 4th gen Nano when my old 3rd worked so well.

I would love an answer to this as well. My 4th Gen plays through my peripherals but won't charge. Even the Apple brand power adapter (firewire) won't work.
