POI'S and Bitmap icon

 

I have a garmin 340..I have loaded sum poi's for Tim Hortons and also a TH Icon..I used the new Beta loader and included the Alerts when I approached TH..Set it at 1000 feet..That works great but upon arrival i do not see my TH Icon?? I made it 30x30..Any ideas on why I cannot see the icon?Thankx
