bluetooth handfree, hbh-300 vs. parrot?

Hello,

I'm looking for a new bluetooth handfree solutionto replace a dying SE
HBH-60. As I use my current headset only for driving, I am considering
a dedicated car kit versus a new headset. I'm especially interested by
two solutions: the parrot CK3000 evolution car kit, and the SE HBH-300
headset. My main concerns are audio quality, as my vehicule is a noisy
diesel van often driven on highways, especially regarding noise and
echo reduction (for the people on the other end), and voice dialing
reliability. I would be helpful for me to read from those who have used
these two solutions in noisy cars, or suggestions for other
alternatives that would be adequate.

TIA
