Thanks Kelly for the info. I did try and calling my local BMW dealer and you would think for such expensive cars they would try to sound intelligent. The guy was clueless and told me to look at my owner's manual - which I did. I know there are spots for the
top tether in my car but finding someone to install it and it not cost $$$ may be another story.
Anyway, I'm tempted to try the Frontier but still scared of the belt path issues and will still need to get the
top tether. I think at this point the
Radian 80 may be the best choice or the lesser of the evils.
Thanks again!
Jennifer
