And forgot to say, no codes or passwords involved and once paired it will, as expected, connect automatically every time you turn the ignition on.
Technically yes, practically no. Bluetooth is almost as flaky as when introduced around 16 years ago I have found.
Maybe Richard. But in my experience and particualrly with our cars (Jaguar, Volvo and Morgan) Bluetooth is pretty good nowadays. My iPhone hasn't failed to connect automatically to our cars in my memory (not that long then some might say

) Are modern installations more robust/stable in terms of connection? Perhaps. And at least Morgan seem to be on the same level as larger OEMs.
I guess it's down to personal experience Ian but present issues with my Android phone and Sony Bluetooth radio involve getting a music streaming connection with ignition in Aux then failing to re-connect after engine started or having music playing through phone speaker. Not connecting after a period when not used, needing to pair devices again etc. Generally ok after a connection is made and maintained but recall one instance where it dropped out on our Mini's audio system whilst streaming and refused initially to reconnect.
Easy to blame the devices but had similar flaky connections with Windows laptop, tablet and many phones working under a variety of OS over the 16 years or so I've been using Bluetooth connections to a wide, diverse range of other devices. As I suggested just my experience over many years but too many issues to ignore.
