I have the Z1-Z3 and for some reason I loose the GPS signal now and again. I shut the car down in the evening, next day, no signal. Tried rebooting, no luck. Next day all back to normal, this set is unreliable, does any one have any ideas on this?

Location of the GPS antenna ? Bad connection ?

"Location of the GPS antenna ? Bad connection ?"

None of the above, like I said it is intermittent and it does not happen very often, you know, like when you really need it.

I have the system for a few years and it happened only two or three times.
