I am new to this forum and have been reading a lot about the different connectors. I have not really been able to find what would work best for me. In the next week i will be picking up my (new to me) 2004 TL with navigation and XM. I have been leaning tward the USA Spec PA15-HON3. I have an ipod touch 1st gen and an Iphone 4. I mostly use the ipod for my music but use the iphone when i want to listen to pandora. Is this the over all suggested device for my application or should i be going in a differnet direction?
