    Predeterminado Long delay to satfix

    When I power on the device in a building or in my car in the garage it takes 3-4 minutes until the Avntura gets a sat fix. This is not what I expected to see and my garmin zumo is much faster in acquiring a sat fix under the same conditions.

    The chipsets have different preferences. Some chipsets get a faster fix (by example from MTK or STM) and other chipsets do better working in the case of low speed (by example SiRF). A universal chipset wit all desirable preverences don't existing. In German: Bei den Chipsets gibt es leider die eierlegende Wollmilchsau nicht!

    I noticed very different result in different moment,
    first time i turned on the aventura, static position in a building without windows(!) 10 seconds to fix the position (Incredible!)
    Some time outdoor walking at 2 / 3 km/h the aventura needs 3 or 4 minutes in open sky situation, sometime 3 seconds... i don't understand very well what happen some time. One time i tried to turn off and on and the fix hase been done in 10 seconds.

    I can confirm Tatos observations. The same on my device, under same conditions the time to satfix can differ etremely.

    I confirm Tatos and Nrgetic observations too. The same on my device, under same conditions the time to satfix can differ extremely. And when sats are fixed, in the firsts minutes (1 or 2 minutes) the accurate is very poor and the track "go and come".

    I'm using a Garmin 60CSx with a SirfIII-Chip.
    Also the same as the Aventura use.

    Sometimes I get a satfix after 30 sec, sometimes first after 15 min!
    That's normal.

    At the moment I wait for my Aventura and not for a satfix.

    Before I had the Aventura I used a Garmin Zumo and I never had to wait 15Min. to get a Satfix. I was getting a Satfix within a couple of seconds, everytime under open sky.

    No answer?

    It would be nice if one of the Compe member would give an answer to the question of the gps-firmware-version.

    Thanks
