It's not clear to me how Speedtrap works on a GPS:
1. Does it make the GPS alert you when you're approaching a speedtrap?
2. Does it display the speedtraps on the main GPS map as you're driving?
3. Or does it just provide a map you can check before you start driving to locate speed traps along your route?
If it does both (1) and (2), that's ideal. If it does just (1) or (2) but not both, that's okay. If it just does (3), then that's less useful.
Thanks for any info.
