car bluetooth connectivity issues

when i try to connect to my honda jazz audio system through bluetooth. It got paired. But gives critical error most of the times and car audio system either hangs or reboots while connecting. When call is received does not display caller name. Phone book got synched. But names are not saved properly in phone book. This was seen both in jolla phone and Intex aqua fish. Can someone from Jolla answer whether this issue is addressed in upcoming build or if not is it planned for future builds.
