3. Update the firmware: Your head unit may have a firmware update available that can resolve the issue. Check the Clarion website or contact their customer support for more information on how to update your firmware.
4. Replace the head unit: If the above steps do not resolve the issue, the head unit may be malfunctioning and may need to be replaced.

Please read my post here: http://community.crutchfield.com/forums/p/22187/251957.aspx (pasted below).

I hope you bought your unit at a Clarion dealer....

Hi, (Team Crutchfield - please add this to your knowledg-base.)
I'm on my third NX501 (could have been the fourth if not for working directly with Clarion).
The SD Card corruption causes both loss of Navigation and intermittent Sirius start up (it'll never acquire signal).
Your unit needs to use the exact micro sd card it came with forever (it has a permanent serial number).
You have two choices:
1. Get Crutchfield to replace the unit
2. Call Clarion (I suggest this rather than ripping your dash apart over and over).
Here's what to do. Contact:

Ben will have you send your microsd and rebuild it for you and return it (likely with the firmware upgrade that addresses this issues on another microsd that can also be found here: http://clarion.com/ca/en/support/navigation_updates/NX501Fupdate/index.html).
While you're at it, update the Bluetooth firmware too: http://www.clarion.com/us/en/support/software/NX501/index.html
Once you get the card returned (THIS IS HUGELY IMPORTANT - EVERYONE WITH A Clarion NX501 SHOULD DO THIS!!!), back it up using Naviextras toolbox (the program clarion uses for map updates). You can get it here: https://clarion.naviextras.com/shop/portal/downloads
Once you follow these steps, barring your micosd physically or logically self destructing, you'll have an NX501 that's nearly problem free and backed up just in case that unfortunate corruption reoccurs.

Of Note: Ensure you insert the microsd card with the contacts facing up and do not force anything.

I'm extremely confident this will make a world of difference for you (and anyone suffering the microsd corruption of the Clarion NX501).
