<p>After repairing my hardly crashed Mavic Pro, I encountered this error: &quot;Navigation system error, check redundancy state&quot;, and here's what I did to clear out this error:</p>
<ul>
<li>IMU calibration</li>
<li>Compass calibration</li>
<li>Vision sensors calibration</li>
<li>GPS board replacement</li>
<li>Firmware refresh V.01.04.0500</li>
</ul>
<p>But none of these worked! And I'm just hoping I can find some other solution before going through IMU replacement.</p>

# DJI Mavic Pro Navigation System Error, After Crash

(Asked by: username_0 on 2022-06-20)

After repairing my hardly crashed Mavic Pro, I encountered this error: "Navigation system error, check redundancy state", and here's what I did to clear out this error:

* IMU calibration
* Compass calibration
* Vision sensors calibration
* GPS board replacement
* Firmware refresh V.01.04.0500

But none of these worked! And I'm just hoping I can find some other solution before going through IMU replacement.
