Tested the latest WP version today, It works now in "Transponder" mode on the transponder number entered.
I noticed a few things
1. It will call out in seconds the time you cross the loop since you where last on the track. She will say one thousand two hundred blah blah blah
2. Listed laps favour the oldest laps and scrolling down will not stick, it just bounces back to the oldest lap times on the top.
Great work Torg, your the first developer to support WP in RC I recon.
