i got a 05 tsx no nav and i got the isimple hook up to the aux of the factory radio and i just got the kenwood kvt 512 and im gonna install the deck and i was wondering is it possible to hook up the isimple and the new deck into the aux at the same time?

 

how is the isimple output set up? if it's RCA's, and the kenwood deck has an RCA input, you should be able to pick up an RCA splitter and it should work just fine... But i do not know how the AUX input in your car works, nor the isimple...

 

the simplest way may be to modify the harness on the iSimple to be able to switch the pins that carry the line level signal between the deck and the iSimple...

I wonder if you could run an iSimple and SNHOND3 at the same time (it uses the CDC interface) and use this to tie it together: http://www.logjamelectronics.com/piex3hon03.html

* I do not know how the iSimple interfaces, so do some research before you buy anything *
