Hi Chaimb69,
Thank you for posting in the community! I understand your Polk MagniFi 2 isn't automatically updating its firmware through the Google Home app.
I can confirm that for all devices with Chromecast built-in, updates are handled automatically by Google's servers when the device is idle and connected to Wi-Fi. There is no manual update button in the app.
If the update is failing, please try these essential troubleshooting steps to force a connection check:
- Unplug the power cable from the soundbar and the sub-woofer for one minute, then plug both back in. This forces a system-wide update check.
- Ensure the MagniFi 2 has a strong Wi-Fi signal where it is located.
- Open the Google Home app, select the MagniFi 2, tap the Settings gear, and check the Firmware Version under Device Information.
If the update still fails after a full power cycle, the issue is likely related to the Polk hardware or specific network settings. In that case, the most efficient next step would be to contact Polk Support for specialized hardware diagnostics.
If you have any other questions about Google Nest products or need additional help, just let me know.
Regards,
Humberto
