The other option is to remove the phone holder and install the bluetooth phone module instead.it leaves some holes, so you may want to also replace the cubby hole as I did (they take a while to turn up on ebay)
The phone module lives under the carpet in the front passenger footwell and is fairly easy to replace, just needs a replacement connector installed. If ollowed this guide

The bluetooth module is part number 4e0862335 and you can get the, on ebay every now and then for about £150
The replacement cubby hole part number is 4E0863075D has no holes but took about a year of waiting before I got one from germany in the colour I needed
