i really dont want one of those things on my head all day..... a decent one is also kind of expensive, i have other things i'd rather spend money on. i once road in a truck with my boss driving, he doesnt have one of those things either. watching him drive a stick shift, knee holding the steering wheel, one hand on gearshift the other hand with the phone pressed to his ear. the only reason i was ridding with him, i left my truck at the plant (plant was backed up) with another driver.... and he was taking me back to the yard so i could go get another truck and load my 2nd set of farms.
he's my boss so i said nothing, but i did think good grief. all i say is i now keep my phone usage to an absolute minimum while driving. the older DEA500 radio DID have functional, working phone usage.... the DEA700 is NOT an improvement. if the radio has phone call capability it should WORK acceptably.
if it was my truck i would find a way to throw that DEA700 in the trash and install a decent pioneer or kenwood headunit. my wife has a prestine 97 grand prix, i installed a modern kenwood headunit with bluetooth, and i have a 2003 bonneville SSEi for a summer toy i installed a pioneer with bluetooth headunit. both pioneer and kenwood have decent hands free capability and i use it all of the time. both headunits were around 100 bucks each.
one of the things i hate about those blue parrots, the drivers that wear them walk around with the stupid things all of the time. you cant tell if they are actually on the phone or not. annoying.
