My friend has an 02 E53 without NAV, he has the 16.9 colour screen with TV. Is his car prewired for the MK III unit?
Thanks in advance for any advice...

yes it should be a straight swap
all x5's with factory option 602 TV Function are not pre-wired for Navigation. If he would like to install navigation, he must purchase the retrofit harness for TV to NAV computer. and then the NAVI takes over control of the Board Monitor.
