I want to integrate my ipod without adding a screen or anything...

but i want it to sound REALLY good (better than tape decks, and fm tramsmitters for sure)

 

do you have a CD changer? Tap into inputs that run to head unit. Cheap, simple, and only requires either 2 DPDT switches or 1 QPDT switch.
A quick search will show other methods.

 

Just look at Puredrifters thread, he helped me with the basics but i went a different way

 

I looked at it but i dont have a naka or a ML audio setup, i just have the totally stock one (I think its bose...?)

ALSO, i dont really want to get a head unit, but how will it tap into an aux channel if there isint one already? (Would i just press the cd button adn i would be able to hear my ipod?)

 

VAIS makes IPOD integration units...

 

Don't quote me on this, but does it really matter what system you have? I mean as long as you have an amplifier and CD changer i think you should be good. AGAIN don't quote me on that, its just a speculative guess.

 

the application guide doesn't say it will work for a 99 gs

 

it should work as long as you have an external CD changer (pretty much all Lexus models pre '01)

only for post '01 models.
