I picked up a 2009 Jag XF, had it for a few months, discovered a few hidden features (like holding down "mix" to mix the entire USB), and I'm wondering two things.

1. Is there any way to have the display on the guages show the vehicle speed instead of the time?

2. When using my phone hands free with the jag, people seem to have a hard time hearing me. Does it still use my hpones mic? Do i have to dial using the navigation? Does it jsut suck? Where is the mic even located in the car?

Thanks!
