i sound gurgly/distorted to people i call via iPhone 3G bluetooth connected to lexus hs250. i've recorded several variations by calling my voicemail and leaving test messages:
my 3G from my car - i sound distorted
my 3G from another car with bluetooth - sounds fine
another 3G from my car - i sound distorted
a 3GS from my car - sounds fine
other phones (not iphones) bluetoothed to my car - sounds fine
I've tried following phone reset, wi-fi off, network settings reset - all with same result.
I've tried removing the pairing at both ends (car and phone), re-establishing - same result.
I've tried from several different locations (maybe with varying cell reception) - same result.
I've not (yet) tried my 3G from another car like mine, but will arrange this with dealer.
Sound from other party (what I hear at my end) sounds fine.
Audio from my phone (via iPod app) bluetooth to car sounds fine.
the distorted sound is very consistent (i have a dozen different recordings on my vmail); best i can describe is gurgly; it's intelligible but annoying.
called apple support. empathetic but no help - only conclusion is "iphone 3G bluetooth hardware may be incompatible with my car's hardware" based on my experience that another 3G sounded the same and another 3GS sounded fine.
