my unit has been working great but over the last few days the gps signal has been very flakey, sometimes i never get a signal, sometimes i get a signal after 20 minutes and other times after exiting igo and going back in a few times and then waiting a few minutes it finds a signal.

it used to be that it would have a signal as soon as the car was started, i've not changed anything and still park in the same places that i did when the signal was instant.

any ideas?

thanks.
