Spent last night running a 5m USB cable from the Speaker pods to the Dash.
Being a bit tight I did not get the Renault speakers and Bluetooth stuff, rather fitted some stand allow speakers in the Twizy speaker pods and power them via a USB cable plugged in the front.
So now I turn on the ignition and my Bluetooth device (Phone) connects and I can play music etc. All very neat, no holes in any panel no switches.
All secure. Okay not going to compete against the Boy racers but allows me to listen just fine.
