Hello, Have you heard about Qstarz BQ-818X? http://store.yahoo.com/semsons-inc/qsbtblgpsre6.html It's a 66-channel Bluetooth GPS receiver with MTK II chipset, -165DBM, A-GPS, 42 hours of operation and Auto-On/Off functionality? Does this receiver would work well with Loadstone, especially for pedestrian use? Przemyslaw
