can now read text messages but cant reply. iphone 4 Ios6 update
 

So I updated my iphone 4 to OS6 software. I then under the synced car multimedia device turned on notifications.
I now get text messages through my BRZ HU but I cant reply through HU. the option come up i hit send and it fails, any ideas?

iOS does not support the send message functions in MAP, only receive. This has been reported with other manufacturers as well (I have seen BMW and Ford Synch users having the same problem).

thank you for the info

Ouch, ok, one would think finally catching up to the pack with MAP support meant full MAP support. Sigh... oh apple you...
