Pilots who notice that the MFD scroll from tab to tab is not working, check for the following:

Are the Tabs along the bottom yellow? 

- if yes, the software card has become corrupt (via the USB port), or the compact flash card (internal) is no longer working correctly.

- Avidyne recommends that pilots replace the USB drives with 2GB drives available on Amazon, or other online electronic retailer (i.e. Newegg)

- specific details on the USB Drives are here: https://avidynesupport.happyfox.com/staff/kb/articles/357-ex5000-mfd-usb-drive

- Pilots will need to work with an Avionics shop to obtain a replacement CF card for the MFD

If the tabs are not yellow, is it difficult to scroll along the bottom tabs?

- this could be the encoder knob in the MFD

- Pilots will need to see their Avionics shop, the MFD will need to be returned for repair. 

- Pilots are encouraged to have an AeroPlan Warranty, as repair cost are extremely high (all cost are provided to the shop).
