My son is installing the Vaistech xm and ipod adapters in my new 400H tomorrow and he questioned where the antenna should be located. Any suggestions? Thanks in advance.

 

In my last car it was installed on the roof right above the rearview mirror - front windshield area - about 4 inches back. The small wire was routed inside the windshield gasket the down inside the door gasket and then behind the dash. A small piece of matching silver pinstripe tape made the black wire invisible on the silver roof.
