Hi - I'm a newbie here but am really interested in finding out more about how to get XM in my Highlander - my Highlander Hybrid is on order and will be delivered 1/2/06. I've ordered it with the factory installed GPS navigation system. But I rented a car last week with XM and I'm in love! Now I'm trying to figure out, since Toyota doesn't offer factory installed XM, whether to cancel the order for the nav system and install one of those does-it-all units (Pioneer makes one), or whether this Factory Interactive XM can be installed in a Highlander that already has the GPS system. I'm looking for something that doesn't "look aftermarket". If I'm going to spend this much money on a car, I want it to look good! Can this XM be installed in a Highlander with GPS, or does the GPS take up all the dashboard "real estate"?

TIA!
