I have not seen this topic here yet.

I have a 900BT. I made some custom POI groups and uploaded them to a SD card using AVICFeeds. The first time I put in the SD, the GPS displayed the list from the SD with no issues. I see it (the AVIC) creates three more files for each POI group.

Subsequently, I uploaded some more POI group files to the same SD card. When I put the card in, it does not show the new POI groups nor does it make the three new files for the group - it just displays the old groups from the initial insertion. I have not tried deleting the three files it creates nor trying to reformat the card (hoping not to lose the POI groups already on the card).

The manual also says nothing on this issue. Any suggestions on getting the new POI groups to read?

Thanks!

I think I got my answer - the SD card needs to be completely re-formatted ever time you want to add more POI groups per Pioneer tech support.
