Hey Gearhead--When I started this thread I was really concerned about a lack of HD Radio capacity in the Terrain. The quality of HD Radio fidelity is quite remarkable and I used it almost exclusively over Satellite & regular FM in the Bimmer. I still use it when not driving the Terrain and will continue the quest to find an add on module to the Pioneer/Alpine unit w/Nav when availabe for my car. Ideally, it would integrate right into the infotainment system of our car, leaving the USB port for other accessories. From what I read and hear, many FM stations will convert to full HD over the coming years anyway. Does anyone know if HD Radio is integrated into the 2010 LaCrosse or Caddy SRX?? Looks to be similar , if not same, head unit.
