Ok, it depends on what outputs your phone is capable of? The B9004 unit in the T180 will not receive high(er) quality audio over bluetooth (A2DP). The later units will. (B9017 for example). Does the phone have a "standard" 3.5mm or 2.5mm audio output socket or similar? As Anchs says there is no aux input. There is in later EU market RAVs. Just to clarify US headunits and setup are different. If you are not to bothered about getting the best audio quality the system will allow, one option would be an FM transmitter based thing e.g.: http://www.amazon.co.uk/s/?ie=UTF8&keywords=fm+transmitter+for+ipod&tag=googhydr-21&index=aps&hvadid=10153155286&ref=pd_sl_4udb3fgsxh_b which might be the simplest option. Otherwise, you will I'm afraid have to pull the satnav out and plug something in the back. Toyota do an ipod only adapter. You won't get ipod text displayed with it on that satnav though I believe. There are several manufacturers of aux input boxes that plug in. Not an exhaustive list but two that spring to mind: http://www.connects2.co.uk/ http://www.gromaudio.com/index.html I had an old connects2 aux adapter that was incompatible with that headunit. I've played with the grom unit. Good spec on paper, but it was slow to respond. That might give a bluetooth option too. There are other adapters. I'm sure other members will advise.
