Thank you, Mike and Antoine... followup, please... when you turn the car off and get out, does PIE FRDW/PC-POD2 stop the iPod's play and power down the iPod? And when you're using the Nav sysem enroute to a destination, and you're listening to iPod music, when using the PIE FRDW/PC-POD2, how do the voice prompts come through the music, does the iPod music fade down for the factory nav system's guidance voice prompts?

Same questions regarding the PIE X3: I imagine when you turn off the car, X3 does not stop the iPod's play or power down the iPod, right? And what about navigation voice prompts when listening to an X3 music source-- how do they come through the factory radio and does the X3 input fade down to give priority to the factory nav system's audio turn directions?

The main feature I'm trying to achieve is automatic iPod music to fade down for navigation voice prompts in the Ford Escape... If FRDW/PC-POD2 or X3 can do that, I'll settle for the factory nav for now...

but I vastly prefer the navigation of the Garmin Nüvi 360 (with Bluetooth cell phone integration) nav unit. I have the Nüvi + PIE auxiliary input setup in another vehicle... and the Nüvi does have an audio output jack and nav guidance voice prompts and cell phone conversations sound great through the factory radio but I don't think the Nüvi has an audio input jack... In terms of getting the Nüvi into the Ford Escape, I can see that the PIE X3 would give me an input for the iPod's music AND the Garmin Nüvi's audio but I guess I would have to manually switch among the inputs.

Am I missing anything here, guys? Do you see a good way to add the Garmin Nüvi, listen to iPod and have nav guidance voice prompts come through automatically in the background? I imagine the desire for superior navigation and better integrated iPod functionality is why some people are choosing to replace the entire head unit/ nav / cd changer. Thanks.
