I recently picked up a 2008 Ford Edge Limited AWD with Navigation & Sync from Koons Ford in Sterling, VA and I've enjoyed it so far, except the navigation system has a remarkable level of static in it. It starts and ends with static and the voice sounds a bit rough, beyond turning it down so low that it's hard to hear, I've been unable to find any workaround that lets me hear it and sounds tolerable.
I brought it back to the dealer and their reply was that it was supposed to sound like that and as I already know, if I turn it down, the static is gone. Granted, you can barely hear it the voice, but at least you can't hear the static. Is this just a flaw in the navigation unit? I cannot believe for a second that in a vehicle that's generally this good, they would just toss it onto the sales lot with such a poor navigation unit. It all strikes me as implausible that Ford engineers were saying, "Let's try to make this one really great, maybe nobody will notice all that static!"
