I'm considering getting a JVC HU. They have program which creates files in PSD format which get uploaded as POI files.
I have no idea how to convert a file into that format.
Does anyone have any thoughts.
Google tells me psd is normally photo shop format.
EDITED TO CORRECT FILE TYPE EXTENSION
PSD files are Photoshop. They would have no relation to POI files. Something strange here.
I may be way off since it took me quite a bit of Googling to even find that HU means Head Unit.
I agree that PSD is a Photoshop image file extension. For cameras that contain GPS, I believe the EXIF data for images includes GPS coordinates. My old Photoshop (v7) preserves EXIF data from a camera's image file when image files are saved as a .psd file.
Is it possible that this JVC program can create a POI from the EXIF data in a Photoshop .psd image?
Maybe if you gave us the link to the software you're asking about, we could offer more advice.
It's a psf file. There were a couple of GPS formats which produced PSD files. As far as I know PSF is only a photo shop format.
I NO LONGER NEED ADVICE. It appears the 2012 units doesn't even off the limited custom POI support offered by older models.
More information. JVC has a program called street director assistant. It allows you to select a POI from google maps. It creates a PSF file on a SD card. The SD card is inserted in your JVC head unit and the the PSF file is used to create a POI.
I was hoping I could convert POI in standard formats over to this format.

If not, post a sample. Maybe someone could offer a crosswalk between the two formats.
I don't know if the file is literally encrypted but it's not stored as ASCII /text.
I'm not buying the JVC unit and I'm not even sure if the current models can even import the limited POI support previous models offered.
I haven't found any program that will read the file psf file.
No reason for me to pursue this. I'll try to find answers if anyone needs help otherwise I'm done.
In reality, the file extension is just part of the file name. Windows likes to use it to decide what program to use to open a file. For example, .txt files are normally text files and are often opened by notepad by default. But you can change what opens a txt file by default, or send a txt file to some other program without changing the default.
psd has long been used by Photoshop as an extension. But that doesn't stop others from using it too (or using some other extension that is already used by some other program), it just makes things a little more complex for the user who depends on a default behavior. In this case it just looks like JVC picked 3 letters that were unfortunately already in use, but the actual file is likely a POI file is a format that JVC defined and has nothing to do with the Adobe format.
The simplest thing to do would be to examine a JVC POI file with this extension. With any luck it might be a text file that cam be easily understood. Or, with less luck it might be a binary file rather than a simple text file, but the file structure might still be apparent when the file is examined with a "hex editor". Or, you might be able to find or get someone at JVC to give you the specification of the file structure.
Can you point us to a sample JVC POI file that we can download and pick through?
