My wife has paired her Pre 2 with the Bluetooth thingy in our Honda Odyssey. It worked fine for 18 months and then it just stopped working well. The level of the audio dropped to a barely usable level. My Pre 2 paired with the car works fine, no level problems.
I really don't want to doctor the phone to reinstall the bluetooth stack since she has apps that are no longer available in the catalog, is there a way to install just the bluetooth stuff? Do you think it is software or hardware?
