I started with a 310-Bt and it was a great unit. It was such a great unit that it created an addiction to mobile technology. So as soon as I heard of the "so called flagship Z110BT" came out I purchased it. Everything works great accept the reason I need it most:
9 out of 10 callers say I sound muffled. I'm in steel sales and I'm on the phone all day quoting, buying, and, selling. I spent over a grand and when you call Pioneer they act as if their doing you a favor by speaking to you. They offer no help suggestions or how's about I'm freaking sorry.
Info you should know:
Phone: HTC Hero Sprint: Phone worked great with U310BT, JVC KW-NNT3HDT
HERE COMES THE ADDICTION PART!!!!!
I became so enraged with the unit that I pulled over one day had it ripped out and installed a JVC KW-NT3HDT and the Bluetooth is FANTASTIC!! The JVC is a great unit but it's screen is smaller and I like the look of the Pioneer unit.
Due to my addiction, yesterday I had the unit swapped again by a better installer and the pioneer is doing the same thing, so it can't be the phone.
All I want is for callers to hear me clearly. Now I have a 310-bt, JVC KW-NT3HDT, and a Z110-BT.
