Is there a way that i can update the bluetooth software?

It doesn't take the calls properly and i cant even stream music anymore. I use to be able to do those things very easily in my 2012 TL. But now my MDX doesn't like my phone.

 

Without knowing what year and version of MDX that you have and not knowing which phone that you have it is impossible for anyone to comment.
BT firmware is not upgradable.

So it used to work and now it doesn't? Apple are famous for updating your software without your permision and dumping some features.

 

Do you have iOS 5 ?

The new OS screwed up a lot of pairings with Honda/Acura vehicles. Best thing to do is delete the phone from your car's system and re-pair it.

 

I do have Ios5. so just delete and repair. What if i try to roll back?

 

I have deleted the phone from the MDX and then repaired it. Nothing.
Its driving me crazy.

 

I am going to take it Acura to see if they can remidy my situation.
