Is it possible to Fastforward, rewind through songs using Steering wheel controls on a TL-S? when i hold down the "next track button" for a couple seconds it takes me to the next disk.

 

I had the same question, My friend has a 2007 TL with Navi and is able to switch CD's by pressing and holding channel on the steering wheel.

 

I'd like to FF or RW with the steering wheel in aux mode with my mp3 player. Is that possible?

 

If you're only using the AUX jack, then it isn't possible (as the AUX jack does not provide control of the attached device, only takes the audio).

If you're using something like iSimple... well I'm not sure, I don't have iSimple yet.

 

but is it possible while playing cds?

 

it should be possible, I can hold the + or - button on the radio and as well the steering wheel...

 

On my '05 TL, pressing and quickly releasing the "channel" steering wheel control (below the "mode" button) will skip to the next ("+") or previous ("-") track on a CD/DVD.
