Hey guys, I needed help installing the iSimple unit on an 05 TL w/Nav. I tried looking, but is there a write up with pictures that shows what to do step by step. Also would you recomend that make/model, or is there a better one out there. It's only $45 http://www.amazon.com/gp/product/B004CZCZ9S. I am new with this stuff, so all insults are welcome

 

Check the other current iSimple thread for a ton more info. They have a more expensive unit that adds an additional headphone plug connector. Also, I'm not sure this unit is compatible with the Navi cars w/XM. Nonetheless, once you choose the right unit, you can definitely install it yourself if you are a little handy. It's a bit tricky to hookup the harness, but there are good methods described elsewhere in this forum. Good luck!
