I have an iphone 4 and it has connectivity issues. It takes a few minutes to connect. Then when it finally does connect sometimes it will just disconnect for no reason. Then when you want it disconnected sometimes it will just connect for no reason despite the fact you are in handset mode instead of handsfree. Very annoying to say the least

 

unpair your phone, reboot iphone, re-pair phone

 

try going to your bluetooth options and turning off AV controls. I found my blackberry was having the same issues until i disabled this feature. If that doesn't work, turn off Audio streaming as well.

 

Turn your wifi off while using bluetooth. Bet that fixes the disconnect issues.

 

I'm going to give this a try... thanks for the suggestion.

 

I did this and it worked for some of the issues I was having, a pain in the ass to have to do all the time though. Plus it didn't fix one of my biggest complaints and that is:

sometimes when I have it on iphone setting use the phone itself instead of the bluetooth, it will connect itself until I disable it for the 2nd time. So when a call comes in it is first in bluetooth, then I turn off the bluetooth and put it on the iphone itself I then use the phone to talk. After like 2 minutes it will connect again to bluetooth without me telling it to during the same call. So I then disable it again and it most often will stay disconnected until I MANUALLY connect it back.

It should just stay where you set it then reset when you hang up. Once you hang up then the next call should be bluetooth, but with mine it stays disconnected. They bluetooth in my IS250 and Tacoma of all vehicles, worked flawlessly and this TSX is a total pain in the ass. I love the car in most areas, but it does have a few bugs that drive me up a wall, the other are all the damn rattles and clunking noinses this thing has
