Is there any possibility to change the map pin color if you have three different maps? Kind of red, green, purple etc?

Not without some kung-fu. If you want to attempt some hack-a-thon in the objective C, lemme know, I'll guide you through it. But, realize that changeing the source in your project means you'll need to do this again if you re-download the project for some reason. It's super simple to change the pin color: See BT_screen_map.m in the BT_Screens folder. Look for this around line 510 [annotationView setPinColor:MKPinAnnotationColorRed]; You could easily change MKPinAnnotationColorRed to the other available iOS pin colors (google MKPinAnnotationColorRed for the others). However, if you change this, ALL the maps, no matter how many you have will use this new color. So, you're challenge is to tell the map to use 'this color for this screen and this color for that screen' Hope this makes sense.
