I really like the look and feel of my stock 04 head unit but i have no way other than fm transmitter to use my phone for music. I could install an AUX but i would much rather have a bluetooth input. I would rather not have to install a flashy aftermarket head unit. Is there any way to get bluetooth through the aux in on the factory head unit or even install a later model head unit with a bluetooth input? I have done some searching around and asking at audio places but cant get a good answer.

Thanks!

EDIT:
Im really just making this post to see if anyone else has attempted this and bounce some ideas around. So far im looking at:
