Aux for 2005 Aston Martin DB9??
 

I just purchased a 2005 DB9. I regularly listen to my iPhone 6 in my current car, but it has an aux port. I have read about the different integrations and they seem rather complicated and I would rather not rely on a crap FM transmitter. Some of the aux kits indicate compatibility with 2006 and on, but not 2005. Has anyone successfully added a. Auxiliary input in their 2005 db9? If so, what would you suggest?

Thanks!
