GlobalTop HD100 GPS heads-up display is pulling a formal review over at DigitalReviews. This is the same Bluetooth GPS receiver with speed alerts that we went hands-on with in March. This highly portable navigation stick packs a MediaTek chip capable of a 1 second hot start acquisition time or 36 seconds cold. Although they have yet to take the device on the open road, they've already found the bright and constantly blinking LEDs (even after GPS and Bluetooth device acquisition) to be rather annoying and likely distracting during nighttime use. The device also requires that you stick a reflective film to your windshield before getting your HUD on. Fortunately, the two included film strips are much smaller than the early prototype we saw at CeBIT. The worst news? We'll have to wait a few more weeks before they get around to testing the device on the open road. Worth the wait to see just how well the device hooks into the navigation software on Bluetooth-equipped phones and PDAs.
