On 2007 TL non NAVI there's a connection for an Ipod as shown in some pics. Is it a special type of plug that is used for the IPOD or is it only a common jack plug that will allow you to plug any mp3 player ?

If no is there a plus to connect an Ipod compare to other MP3 playsers ? I mean, control by steering wheel buttons or song title display.

Thank you

 

You have been misinformed. The 2007 TL comes with an aux input which works with all types of MP3 players; it is not iPod specific. Since it is a simple aux input, the steering wheel controls (advancing songs, title/artist display) will not work (but volume control should).

Factory-wise, you can add the MusicLink for iPod integration, but I suggest you take a look at the USA Spec.
