2 i believe my stereo cant play apple play is there any way of doing this by a software update
Hi,
go to your car dealer, you need a newer firmware. December 2020 is the version 7 up to date. 
Hi tom-r-howe ,
ok, but normally "Apple CarPlay" should work with RLink V3.x and above...
but to support newer smartphones, is the update to V7.x from the dealer a good idea for sure... 
the Head-Unit is underneath the RLink-screen... but it is a bit tricky to remove the covers and the screen to reach the Head-unit... but perhaps you don't have to remove all parts, only to reach the radio's harness...
But if you only need the speaker's-cable, you could try it in driver's and passenger's footwell underneath the covers from the lower pillars... sorry, I hope it is understandable... 
kind regards
Hey Tom,
R-link2 is a central control device that is attached to the CAN bus and MOST bus. The amplifier is in the depths of the dashboard bayside the R-Link2-Unit, (called „Radio“).
All systems are integrated ones.
Firmware 3.3.15.411 will not work with CarPlay. You should go to the dealer to get Firmware 7.0.24.161.
Ask for „OTS 0D69“.
After installation of the new firmware, you have to activate CarPlay in developer‘s mode.
Regards
Udo
