I have a blackberry 8800, and am bluetooth pairing it to a Mio c520 GPS. All works fine appart from when I answer an incoming phone call, there is a delay of up to 30 seconds before I can here the other persons voice, I can hear it on the phone and then 30 seconds later on the GPS unit. Has anyone seen this before and is there a fix. I don't get the same problem when pairing with by Samsung mobile.
