Hi, looking to swop original head unit, must have android connectivity, blue tooth, run sat nav from phone or internal (prefer phone) usb input to charge phone, I like touch screen but its not essential.
Looking to preferably spend no more than £400 and easy to install, also advice on necessary wiring kit or mods would be appreciated.
Finally, is it worth selling original on ebay and if so any ideas what its worth, everthing works.
