Where can i buy the htd7001 ipod docking station for the phillips cineos soundbar pleas?

The problem is with the speaker connector to your ipod. I have the same unit. Got to ebay and buy Pyle Home PIDOCK1 or similar docking station. This will solve your problem. You can plug this in and have full functionality back of your speaker. Don't bother trying to fix it these have a real problem with the connector and board buy yourself a docking station with remote for about $15 on ebay and it will fix you up. Plug into the input Jack and you are back in business. You can buy a Pyle Home PIDOCK1 Universal iPod/iPhone Docking Station cheap on ebay and it has a remote. It will fit nicely on your speaker and do everything you need it to do.

You can pick up an ipod docking station adapter here.

You can buy an Apple 30-pin docking extension cable from RadTech ($15)

It's a new ipod, right? And your docking station must of been made before the new nano toke the stores. You need to get a new docking station.

I had the same problem but with a different TEAC docking product.
My TEAC would not recognize my ipod therefore I was unable to control my ipod via the docking station remote control.
Plug your ipod into the docking station and power down (reboot) your ipod. Once the ipod powers down (in the dock) restart the ipod (yes, while in the dock).

is there a docking station/speakers compatible for the tevion mp4 (8198/4701/40972?

A 712 is not set up to use an Ipod USB dock.  You can buy a dock that will use RCA jacks into an old stereo - Apple sells them, others too.  Then the Ipod sits up and you can look at it.  Or you can buy the 1/8" stereo plug to two RCA plugs that Radio Shack has been selling for 30-40 years, plug one end into your Ipod headphone jack, and run the two RCA plugs into your Aux input.  That costs about $5, and is easy as pie.  An Ipod will play through any old receiver, but the USB docks will not plug into them.

They both use the same speakers, my personal opinion deems they are both the same. However the second SoundDock charges via USB pin, so it is future proof for future iPods.

for some **** reason the new ipod nano (4th generation) does not support FireWire and therefore will not charge on any docking station that is a FireWire power sorce - which seems to be most of them out there!
have same problem so will end up charging from computer as docking station still plays the new nano, no point in buying new docking station just for sake of charging!

I also have the same problem but now I think it's the type of I-Pod you use. Do you use the I-Pod 80 Gb video or the newer 160 Gb I-Pod with the cover flow etc. ? The documention of the HTD7001 says it's only support some I-Pods. I would know sure if I would have a type of Video I Pod wich is supported by the documentation
