    So as I said,

    If I was in the city doing lets say 40KPH, but the buildings are messing with the GPS signal (I have often seen my tomtom be off by 2-3 streets showing me moving at 15KM).
    What would happen then?
    Defense mode would stay offline until it thought I was at 20KM? or would there be some way for it to work out that the SNR is low and it only has a lock on a small amount of G-SATS so it should disable the GPS filtering until a certain threshold was reached.
    Or would it work it out based on accuracy of location, eg within 20m ok to filter, within 50m, disable filtering?
    EG SNR + G-SAT Lock + accuracy = a point index which is high enough to reenable or disable GPS filtering?
    Defence: ALP x 3 Front / 2 x Angled Rears | Stinger VIP Radar x 2 Patch Panels / Stinger VIP LIDAR (testing)| Escort Redline 2013 int | Escort Redline MRCT 2015 int | STI-R+ | V1 (testing) | Veil
    CM Testing: Spectre RDD Mrk IV | UltraLyte LR UX 125pps | UltraLyte LRB 125pps | Stalker LZ1 | ProLaser 2 (The Hole Finder) | Kustom Talon 2 KA | Bushnell Velocity K Band
    Intelligence: Front/Rear Dash Cam | 477MHz 2-WAY Radio

    Sounds like BRD is saying it most likely will perform as if there were no pre-defined speed limit, like Savvy does I'd guess.

    That is right. If you have GPS enabled but your GPS mouse is unpluged/or GPS signal is not locked - your ALP will behave as if your GPS setting is disabled. If your antenna is plugged in and GPS signal is locked ALP will use speed reading that it gets from GPS whatever it may be.
