Narrative:
Garmin 430 GPS with commercial database indicated R2503C with altitude limits of 15K to 23K restr. It showed R2503B as identical to 2503C when outlined and clicked on. Actually 2503B&C together restrict from the surface to 27K. After speaking to the controller at socal, he suggested if I click on the lower right hand corner of 2503C it would come up 0-15k. I tried it and it did -- too late now. I had violated the airspace. The database supplier should correct their display to show 0-27k restr for the entire area, no matter where you click on the map. I would have never known you could get different restr limits by clicking on different areas of the restr area unless the controller told me.

Title: PLT OF SMA ENTERS RESTR AREA R2503 BACK COURSE WHEN HIS GARMIN 430 GPS FAILS TO PROVIDE ALT INFO SPECIFIC TO BOTH OF THE CO-LOCATED AREAS SIMULTANEOUSLY.
Narrative: GARMIN 430 GPS WITH COMMERCIAL DATABASE INDICATED R2503C WITH ALT LIMITS OF 15K TO 23K RESTR. IT SHOWED R2503B AS IDENTICAL TO 2503C WHEN OUTLINED AND CLICKED ON.

I TRIED IT AND IT DID -- TOO LATE NOW. I HAD VIOLATED THE AIRSPACE. THE DATABASE SUPPLIER SHOULD CORRECT THEIR DISPLAY TO SHOW 0-27K RESTR FOR THE ENTIRE AREA, NO MATTER WHERE YOU CLICK ON THE MAP. I WOULD HAVE NEVER KNOWN YOU COULD GET DIFFERENT RESTR LIMITS BY CLICKING ON DIFFERENT AREAS OF THE RESTR AREA UNLESS THE CTLR TOLD ME.
