All cables may be secured but the internet signal is not enough to keep the modem latched. When it drops too low, the modem lets go and tries to acquire it again. You need to check all the connections and you may have a screen on the modem setup that shows you the signal strength. Keep in mind that any connection your signal travels through causes a loss of signal and the SPLITTER connections are big loss of signal devices. If you lose 3dB it is half the signal

Cleaned all the connectors right under the airbox which I took out with some connector cleaner i got from the local autoparts store and it worked. Try that before you spend $600 on a new unit.

This is an odd fix, but I read it yesterday after having the "Acquiring Signal" issue for a week. I put it in the freezer for 30 minutes, brought it back to my desk and now it works. I don't know why or how, but I am happy.

can you open the case of the phone?
open it, because the internal ground antena maybe unconnect to the mainboard. try to clean the spark on the connectors.

It took about 45minutes of holding on Garmin's tech support line but when I finally got through here's what they'll ask you.

1) Have you tried a hard reset?
-Just push the reset button on the back below the GPS antena
2) Have you updated the software to the most current version?
-Run the Garmin web update utility after you've connected your GPS receiver to your PC via USB. Update the software (current version 5.6) and the GPS Chipset Software (current version 3.0)
3) Have you tried a master reset?
-WARNING THIS COULD ERASE YOUR ENTIRE FAVORITES SECTION. But you turn off the GPS push on the top right hand corner of the screen while you power up the unit and it will ask you if you want to perform a master reset.
After you've done all this (and you can save yourself some time by just doing it before you call) they'll tell you its probabbly a diode in the unit that controls the antena. See that little gold looking hole in the GPS antena? That's where you can connect the external antena the diode the controls where the unit gets its satellite signals from (IE from internal or external antena) is known to mess up if the unit is left in extreme heat (a hot car would do it) however aparently since this is such a common problem Garmin is accepting RMA's for the units even if their several weeks out of warentee (mine was and i just sent it off for this very same reason). More often than not they'll simply replace the unit with a refab and you'll be back in bussiness in no time. Hope this helps!
