Finished installing the unit but the navi is off quite a bit. I calibrated number of times and tried ajusting average speeds but no luck. Arrow on screen travels much faster than my actual traveling speed. I mounted the GPS antenna on top my front windshield. My radar and my alarm antenna is few inches away from it too. It was raining pretty hard today. Maybe weather have something to do with? Any ideas???

call eclipse support line they will help you through it. I believe if you drive the car around it will be fine. We have the customer come back the next day to finish calibration.

What do you mean finish calibration? What needed calibration before/after installation? The unit itself or customer's car?

calibration to the unit once the unit is installed in the car. A simple 2 step process all done by the touch screen. For some reason the unit has to be on for a while and driven it will be quite off. Did you hook up the vss wire? without this it won't work properly either

Can you be a little more specific on the 2 step process?

So you are saying if I don't leave the unit on and drive for a while, navi will be quite off? How long do you recommend driving w/ the navigation on?

What's the vss wire? All the wires were for audio except speed, reverse, and parking.

vss must be hooked up! the others you can test without but that must be hooked up. This will also get your voice commands to come up.Hook up the vss,hook up the parking brake wire (or ground it) drive the car for 1 to 2 hours and recalibrate and enjoy your new toy. as far as the 2 step process it sounds like you have been doing it but things will be waaay off without the vss.

vss wire is the speed wire?

Nevermind. Navigation doesn't even work without the VSS wire. Only thing I have left to do is maybe drive for an hour or two and see if that will fix my problem. Otherwise, I think I just have a bad unit.

From what I understand, you stuck the antenna to the inside of the windshield by your others, correct??? If so, you won't be getting too many satellites that way. Try popping the antenna off of the windshield, and just placing it on the dash, facing up (adhesive down, on the dash). If it isn't seeing a decent satellite signal, it has nothing to reference to (IE:VSS..... it's just a pulse, it doesen't know how fast you are going, it just needs the VSS to see the vehicle moving, and to calculate against actual satellite data)

Try it......
