I have a 2008 Toyota Tundra with the bluetooth built in.  It worked great with the original iPhone.  Callers could not tell they were on speaker phone.  
Now I had a couple iPhone 3G calls over the same system and:
1) I can hear my own echo (but not the other end)
2) The other caller tells me I'm breaking up.
Anyone else experience similar problems.
