My understanding of the tx head is that it requires the ALP CPU to be connected to the GPS antenna, and that's for IP protection.

My guess is that it's harder to reverse engineer the thing if a requirement is that the sensor has to be moving at a particular speed or higher. Anyways, (since I don't care to reverse engineer duck all), my question is more from a usability perspective.

Let's say I'm speeding in a tunnel, and there's a cop who dings me. Since the GPS receiver can't connect to a satellite...

1) I guess I'm screwed because for all intents and purposes the ALP thinks I'm not moving? Am I right, wrong here?
2) Is there a way for me to know if/when the system is actively ready and alert?

Right now (I don't have the GPS unit), when the ALP system is ready/active then it goes blue. I assume that at a speed below 30km/hr (since I'm in Canada), it doesn't go blue, and once I go pass the minimum speed it then does go blue to alert me it's ready?

Am I off base here? Thanks
