This is the latest version of the phone holder for my Land Rover Defender.
I replaced the ashtray in the centre of the dash with this holder that I designed for an iPhone 4 in a HEX wallet.
The holder has a slot in the base for a USB / iPhone connector which plugs into a rear USB slot in the stereo.
This set up gives you access to all of your iPhone music, apps (sat-nav etc.), hands free calls on the move (using the wired microphone which came with the stereo) and it also charges the phone, all without removing it from the wallet!
