It truncates all messages after approx. 3 seconds.
This only happens with the Toyota Highlander LTD Platinum, not with our Hyundai Genesis.
The Toyota service manager has tried updating the software in the vehicle but it made no difference.
They tried an I phone 6 on Verizon and it does not truncate voice messages. They also tried a Galaxy 7 on T-Mobile and it did not truncate there either.
