I have a F90Bt on the way that I will install myself.

I currently have a Avic-N1 installed with TV in the headrest connecred via RCA cables.

My question from readin the installation Manual the F90BT only have AV-1 in the back of the deck and I you need to connect the Ipod there... So my question is where am I going to connect my Headrest TV's?

Main reason I am upgrading from N1 to F90Bt is because of Ipod features.

(I am curently using the ipod adapter for the N1 but it lacks features.

Also on side note is there a need to hook up the reverse cable?

The ipod uses the A/V INPUT. The video signal leaving the deck going to headrest monitors is the rear OUTPUT. You're fine
