Since my review of the Ottocast Mini, this adapter has been on the market for almost a year. Still, recent firmware updates have transformed it from a wireless adapter with a simple disconnect button into one of the best multi-user CarPlay and Android Auto solutions available today. After revisiting the adapter with fresh firmware installed, its improved switching performance delivers the experience it should have offered at launch. For anyone sharing a vehicle with a partner or family member who uses a different platform, this small upgrade makes a big impact.
A little update goes a LONG way!
The Ottocast Mini (model CA505-T) differs from its more recent release, the Ottocast’s Mini Cube3, in both design and function. It is slightly larger but includes a physical multi-function button, which originally served more as a reset/disconnect button than a true platform switch. With the latest firmware installed, that same button now triggers a controlled reboot that switches the adapter between iPhone and Android devices, or even between two devices of the same platform. The addition of this functional button finally justifies the Mini’s design over other wireless adapters when choosing an adapter for multi-user switching support.
The Test
My initial testing focused on cross-platform switching. I first had both iPhone and Android devices paired before jumping into the car. Before jumping into the car, I last connected the adapter via Android Auto using my Samsung S22, so it was to my surprise that the adapter had already switched to connecting to my iPhone for Apple CarPlay!
Pressing the adapter’s tiny button caused the adapter to disconnect, reboot and attempt to connect to my previously paired Android device. After a short double-reboot cycle, it successfully switched to Android Auto in 42 seconds. This soon confirmed that the new firmware now handles the protocol change automatically, albeit a little lengthy, but this is to be expected and faster than manual intervention. This behaviour alone elevates the Mini as one of the easiest cross-platform wireless adapters to operate.
Too Good to be True?
To this adapter’s merit, switching back to CarPlay was just as successful. Pressing the button again triggered a reboot, the adapter switched back to the CarPlay protocol, and my iPhone connected without any additional user input, all in a little faster connection time of 23 seconds. What makes this impressive is that the adapter not only changes platforms but also responds intelligently to whichever device is currently turned on. If the iPhone is unavailable, it will attempt to load the previous Android Auto device instead. This type of adaptive behaviour is incredibly useful in real-world shared-car scenarios.
Switching Between Android Devices for Android Auto
To take the test further, I paired the adapter with two Android devices. The switching between a Samsung Galaxy S22 and a Google Pixel was almost instantaneous, at roughly 14 seconds each time. Once paired, pressing the button disconnected the active device and reconnected it to the second Android phone with a near seamless transition. Android-to-Android switching is often an overlooked feature, but the Ottocast Mini handles it reliably.
Swithing Between iPhone Devices for Apple CarPlay
The same test was repeated using my two iPhones, a 16 Pro and a 17 Pro. Each had a different wallpaper colour to clearly show which phone was active. The Ottocast Mini switched between both devices as smoothly as it did with the Android phones. A little slower and Android Auto, between 21-26 seconds. The adapter demonstrated no hesitation in disconnecting one iPhone and launching CarPlay on the other. For families who share multiple iPhones across one car, this performance alone makes the Mini a standout product.
Switching & Good Functionality
The adapter continues to deliver strong wireless performance overall. Navigation remains smooth and responsive, music playback is stable and general CarPlay and Android Auto responsiveness remains comparable to the Cube 3. I even retested its boot-up time, and in Android Auto, it beat recent adapters to the top spot at 13 seconds! The main trade-off is that the Mini remains slightly larger than the newer Ottocast adapter and, depending on the car, may feel less sleek if used in more compact spaces. Its media delay from this update wasn’t tested, but its previous performance was not as low as some newer models, although it remains acceptable for in-car use.
The GOAT of Multi-User Wireless Adapters
The real value of the Ottocast Mini is its multi-user support. When updated to firmware version 2583013072.2 or later, the adapter becomes one of the few wireless CarPlay and Android Auto solutions that genuinely deliver platform switching with a single button press. There is no need for unplugging, forgetting Bluetooth pairings or navigating deep menus. Once two devices are paired, the Mini takes on the heavy lifting and keeps the handover simple. Should you have more than one device, it can pair with the last device used; however, switching between more than one device could be an interesting test.
For anyone sharing a vehicle daily or switching phones regularly, the Mini is one of the most capable adapters currently available. If you already own the adapter and struggled with it previously, updating the firmware immediately transforms its performance. If you are considering buying an adapter that prioritises switching over minimal size, the Ottocast Mini stands out as the most complete choice for multi-device households.
