2013 3.6 was just trying out the update system software- naviextras to determine if there might be a way to add redlight cameras etc and found naviextras will not recognize the SD card from the fujitusi radio. I emailed naviextra's tech support and here is their response
"First of all, thank you for your interest in our products!
We would like to inform you that your device/model is not supported at naviextras.com.
These PNA devices are called OEM (Original Equipment Manufacturer) devices. Due to industry practices, the support for OEM devices is provided by the manufacturer of the product. As you bought an OEM device, please get in touch with the distributor regarding the maps/updates/support.
If the manufacturer of your device is on the compatibility list but your device model is missing, please visit back regularly and contact your manufacturer too. To add a new model to the list we need to test the compatibility and we need to have the permission of the manufacturer.
Please visit back later as the list of supported devices is constantly expanded.
If you have further questions, do not hesitate to contact us!
Best regards,"
I have found many persons with issues with naviextras who utilize windows 7 64bit so I responded to them that it appeared to be an issue with their software...
"This is issue is not because of your operating system. Toolbox doesn't recognize it, and won't recognize it, because your device is not supported by our company. I've checked everywhere if it is, or is there a project for it, but unfortunately at the moment you device is not supported. We would apologize for any caused inconvenience."
I hope this saves all you the time and effort in even attempting to try to get the card recognized or add maps etc.
