As above the later CY17 / CY19 Systems installed in new Rav differ from the earlier Touch 2 system in older Rav where both software and maps where bundled in update twice a year this was easier for updating but also meant "fixes" had to wait for Spring/Autumn map updates before they where released the new systems split software and maps so fixes can be released much quicker
If you press "setup" then on the right menu scroll down to "software update" there are 3 headings
DCU/Audio this is the touch screen audio unit
MEU/Naviigation this is the Media extension unit / Nav ECU
navdb_version this is the map version.
DCU / Audio
On Rav4 there are two Audio/Screen manufacturers if you read the model ID if the 4th from last digit is:
C unit is manufactured by Deson Ten latest DCU firmware is 1215 and includes the following fix
Bad voice quality on Hands Free talk. The far end party cannot hear well and asks again and again to repeat. Symptoms: A-word cutting, B-Muffled audio, C-low volume.
This is due to a double Noise cancelling phenomenon by combined noise cancelling in Microphone and in DCU. SW version 1215 and higher (future) versions of this SW include the C/M to this phenomenon.

MEU Software release version 1530:
Unlogical traffic information (showing 4.5 million km on right side bar)

Wrong navigation guidance speech in Hungarian: translation of word "street" said twice by the navigation unit.
Wrong side of navigation traffic information for left-hand traffic countries.

After ignition on the map view is not displayed and the driver will see a black screen. The functions of the DCU remain fully functional.

Firmware fixes can be applied at your dealer as a warranty repair based on a fix for one of the recognised issues ( a good dealer should do this if asked even without an issue ) or via www.toyota-tech.eu access here is chargeable though.
Map updates can again be done at dealer and should be without charge or via MyToyota account.
