It's Simple! -- When you know how.. start pairing the phone to the radio, but it on phone mode, and have your phone search for new devices, when it asks you for a password, try
2121
or
1313
9780 used to pair perfectly with the manufacturer system on a 2007 range rover sport. Upgrading from 6.00.294 to 6.00.498 results in the phone showing "connection to LANDROVER failed". Pairing appears to work, car is discovered etc, but the process does not complete. Once in about 20 times (of starting the car) the phone will pair and be able to receive calls, but the address book is screwed up.
Downgrading back to 294 and everything returns to normal working 100% - which is what I have chosen to do as 498 had so little to offer.
Because RIM are so unhelpful, it is impossible to ask this question:
"exactly what did you change between 294 and 498 in the bluetooh implementation/code that would cause the problem described above"
well that is strange.. conscious of the previous problem (where it would sometimes pair but then wouldn't pair again) yesterday after upgrading i left the vehicle, walked away, and back again to check it was fully working - and it was. Did this 3 times then got bored :-). Then i just checked again this morning and... still working! Something occurred to me - are you doing a fresh link after version upgrade? I am NOT - i link it in 280 then upgrade to 534 (the bluetooth profiles persist). Could this be the key?
