Navigation Address Book Download/Upload Function

[serverpimp]

I have a 2010 G37 Sedan with the Navigation system. In the owners manual it explains how to upload/download the address book to a USB device. So fare I have entered via the Nav screen 4 addresses. What I had hoped was the file that I downloaded to the USB with my 4 addresses would show me that the file was in just a normal text file that I could pull up in Notepad in Windows. At that point I could pull my address book from multiple sources (Outlook, Gmail, etc.) and insert them into the file; upload via the USB device into the G37 Nav. Wahlah! All my addresses would be listed. No such luck.

So the files are put in a folder called 'userdata'. There here are 3 files: homelocation.hlc & storedlocation.slc & stsfile Can't read them with Notepad. And I can't find anything through Google searches to help me understand the file format, let alone the application that I could use to edit the files.

Anyone know anything about these files? What was Infiniti's intention to build in this functionality, insert it into the Nav owners manual? Surely it can't just be to transfer your address book from one Infiniti to the next?

The part I read said it was for transferring from one Infiniti to the next. Course my 2008 did not have the ability to download so it didn't do me any good. I used the phone upload and copy to build my phone book. It was fairly simple and I can always use the phone address book for those numbers I rarely use.

The files could be in a proprietary format meant to be read by other Infiniti NAV systems. You may need a special editor to create these files locally on your PC then copy them to your NAV.

I have exactly the same question about the navigation system in my 2013 Murano. The easiest way to see the file structure is to change the *.slc and *.hlc extensions to *.csv, and open them in Excel. (If you don't have Excel, you can open all three files with the free app Notepad++.)

There are 30 or so fields in the *.slc file, and they are separated by commas. I can figure out what only two of the fields are: longitude and latitude. There was nothing that indicated where the display name, street address, city, state etc. are stored. And many of the fields have 0's, 1's and -1's in them, signifying that they are probably flags of some kind. The home location file has few fields, but I don't know what the data signifies.

I've been using a standalone Garmin GPS for a long time. This is my first in-car GPS unit. For all its sophistication, I'm amazed it can't import addresses and points of interest as easily as the much-less-expensive GPS units can!
