    Yup, it has to be yours because mine will work if the battery dies out, it will power up right away and start locking on sats, it can standby 48 hours and I drive daily so it always has a lock anyways before the battery ever dies hehehe

    Are you all referring to the q818x? Because I have the q890 and it definitely does not power on automatically if the battery has previously died (it just charges). When I asked about the q818x to qstarz, their response was: "Dear Sir/Madam, No, all of our product will need to switch on manually to power on."

    Hi Hari-Bhari,

    Your Q890 has an On/Off switch that you need to press and hold for 4 seconds before it switches the unit on or off. That switch indeed requires power.

    However, the Q818 has a simple mechanical switch. You can leave it in the ON position, and the unit will be ON when you apply power to it. I just tested it for you. I removed the battery from my Q818, and then I attached the unit to my laptop with a USB cable. The LED instantly lit up, and I was able to use Garmin Mobile PC navigation software.

    Excellent, that's exactly what I needed to know. Now in terms of lock, I am having trouble getting my q890 to lock when it's inside the glove box. Even when I remove it and let it see the sky, the first lock can take several minutes. After that, it locks very quickly. Does the q818x suffer from this same problem?

    I would expect every GPS receiver to "suffer" the same problem. Satellite signals are quite weak, and when a GPS receiver is in the glove compartment of your car, it will in most cases have a very difficult time getting the first fix.

    Look for better location for the unit to achieve better performance. The roof is the ideal, but if that's not possible, place it at least close to one of the windows.

    dam...I'm going to have to get another one. Mine won't power on AT ALL if the battery is removed. Not via USB cable on the pc, nor via standalone power supply.

    i think he meant remove and reinserted. I don't think u can leave the battery out totally, it's needed to complete the circuit usually in these types of devices

    well my old ayay sir ti-gps used to have no problem getting a lock no matter where it was, i mounted it under the top of the dash. i guess i was hoping for same or better performance in these newer units :-/
