I wanted to ask You if there is any way to get rid of the RSA above speed limit beeping permanently? Found some threads on internet but I can't see the 'normal' way for turning it off. So I have a follow up question, Is there any application or something else which gives ability to modify some options which are not given in normal HUD? (hidden features, advanved modes) Thanks in advance. Maciej
Carista has finally been updated for the gen5, but it can't shut off the European RSA beeping. Technically it's only been updated for the Prius and not the Prius Prime/PHV, but it should be a good starting point. You can see what it can and can't do here: Carista At a glance, it seems to be the same stuff that can be changed at a Toyota dealership, but I didn't dig in to see if they're exactly the same. You can find all configurable options towards the end of your owner's manual under Vehicle Specifications -> Customization(section 9.2).
permanently turn off the RSA beeping, you can use an OBD programming app like Carista or OBDeleven. These apps allow for customization of various car settings, including disabling annoying beeps, providing a more personalized and quieter driving experience.
