It appears this has changed. Previously you could only get the 7" premium head unit with nav. Now they are listing the entry level 6" head unit in the base XLE. This should also have a CD player.In the USA, the Rav4 hybrid is available as the XLE or the Limited. All the Limited models have built-in navigation. Most of the XLEs have the regular Entune radio system without navigation. Navigation is an option which upgrades the radio to Entune Plus which has app such as online music streaming etc.
Maybe the only ones you've seen are XLEs with the upgrade to Nav and Entune Plus... But Nav is NOT standard on the XLE hybrids.
