As far as I know, Renault didn't build bluetooth into the head units at the time,
but used an external bluetooth adapter, the Parrot CK4160 or CK4260, if I'm not mistakenů
If the dashtop display and the steering column remote stalk are your only reasons for wanting a Renault head unit,
then there's still some hope in the aftermarket, so read onů
I've fit an Alpine head unit into mine, and the APF-D101RE works a charm with the display.
If your factory head unit model is Tuner List, both Alpine and Pioneer offer a remote interface that also utilizes the external display on the dash top.
The one from Alpine is called APF-D101RE, and the Pioneer one is called CA-D-PI.180.
If the factory head unit model is Update List, however, I've only seen compatible adapter from Alpine, model being APF-D102RE.
In order to utilize the display feature, the head unit must also support this.
Some of Alpine's models have a dedicated connector called "Vehicle Display Interface",
while Pioneer uses the IP-bus for this purpose, so if you choose them, get a head unit that's got IP-bus (because not all models do)
If you're not too fussy with the display, but still want the steering remote stalk, there are more brands to choose from, in addition to more models from Alpine and Pioneer.
Most of the big names in car audio offer units with either built-in bluetooth,
or with the option of adding a bluetooth module that plugs into the back, which you just fit somewhere in a cavity using heavy-duty velcro.
