I don't have Entune so I really don't have an opinion but there's been a lot of Entune bashing on this forum. Follow link below...
Need an opinion about Entune? You can borrow mine. It's terrible, even if does get the highest ratings. I think AAA also rated it most ergonomic and user-friendly a few years ago.
First of all, Toyota has never figured out whether Entune is an integrated system that includes navigation, audio, voice interface, etc., or whether it's just a set of corporate-approved apps like Bing and Pandora. Perhaps it's their OS for the system. Whatever, it's just designed to get the vehicle out of the showroom and into your garage.
Can you update anything? Not really. For example, why on earth would they design a navigation/mapping system that gets updated every decade with new out-of-date information? Any real nav system would be out of business by now. And why do you need Entune to run apps, which require your data source via bluetooth, when you could just use your own device? Would you like to run Apple CarPlay? Sorry, Entune is a closed system. And perhaps it's just me, but interacting with their voice recognition system is like trying to talk with a four-year-old about the structural intricacies of Moby Dick.
Nevertheless, it's a good radio. Sirius was fun until the free subscription ran out. The out-of-date maps are sometimes useful, especially the forest service road mapping that is available even when cell phone service is non-existant.
I have great respect for Toyota engineering. However, the Entune system really isn't a Toyota product. (Panasonic? I've forgotten).
