Neither of those threads appear to apply to a 2014 which has a different radio, and since they have a 2014 they probably aren't still in warranty either.

Is there really a separate Bluetooth module? I have seen replacements for approx. $30 on ebay that state they are a Bluetooth module that would work with a 2014 rogue.
I'm almost certain that's an error - the Rogue Select (identical to the 2013 and earlier Rogue) did have a separate module, but everything I can find shows that the Bluetooth on the 2014 Rogue is integrated into the stereo (otherwise you'd be able to find a separate module for the 2015 Rogue which uses the same stereo).
You can check the FSM here:
https://www.nicoclub.com/FSM/Rogue/2014%20Rogue/AV.pdf - it states "Bluetooth® control is built into audio unit" and there is no mention or representation of a separate bluetooth module anywhere in the document.
You've got a few options.
One, you could try installing the D605 software for the Nissan QashQai. The European QashQai uses the same LCN2_Kai Nissan Connect unit as the 2014-2015 Rogue, and the software is universal for both regions as well. I don't know if I'm allowed to link it here, but just google the D605 qashqai forums and find the mega link in the firmware update thread. That version is a year or two newer than the latest D407 available in the US, and when I updated mine it did increment one of the values shown for the bluetooth firmware version in the software information page by 1. I am running this software on my US Rogue and it is identical to the US software, except that it does not experience nearly as many Bluetooth disconnections/dropouts as I was having before (though I never had the reboots you describe). Just make sure you perform a factory reset after updating.
Two, you could replace the radio with another of the same model. I have seen them on eBay for a couple hundred dollars.
Three, you could replace it with an android headunit. Dasaita makes some that are designed to factory fit the rogue, including adapters so that you don't have to mess with too much of the factory wiring.
