My goal is have separate icons for Shell, Esso etc. My problem is that the only type number that works as gas stations is 0x2f00. I have tried to use numbers in the range 0x2300-0x2310 and 0x4400-0x4410 without success. The icons shows up on the GPS screen but are not categorized as gas stations and are not searchable in the menus. I have a Zumo 660. When I browse the original Garmin map for Europe I see that it is possible.
