I have no bluetooth, no USB, just Aux In...

Is my professional HU is Bluetooth and USB capable ?
If not, where can I find this HU ?
Can you confirm me that I just need to have a Professional HU with Bluetooth and USB built in and no need to install a MULF unit before ?

Thank you by advance for your help
I am not sure dude, but I think your Head Unit is not built-in USB/Bluetooth.
The easiest way to check this is removing it (it is very easy, only 2 screws) and see if there is a sticker with the bluetooth logo on the top.

If your HU is not suitable, you have 2 options:
- Instal a MULF on the boot with all the wiring needed
- Buy a new radio with all the features (No Mulf is needed )

I think the best way is the second one. it is cheaper and easier (I did it), but you could have problems if you have to recode your car at your dealer (if you have to change any ECU for example) but you can put back your old HU and problem fixed.

I bought it at eBay, there are several HU around 300€. The rest of the stuff (mic, wires, sockets) can be bought at your dealer for 100€.

Why don't do it by your self?
Retrofitting is always possible!
