: Removing Dash for GPS Antenna Installation

Hey guys,

I'm putting in the NAV system into my car, and had a question about mounting the GPS Antenna. I saw a picture on here where there was a metal plate near the top of the dash that the antenna sets on. How do I remove the upper pannel to get to that location? Is it just a whole single panel on the top that prys up? Thanks for the help.

another question, I went back out to the car a couple of minutes ago, because I remembered that I did not hook up the radio antenna to the new unit, and when I got in to the car, i hear what sounded like the Nav DVD rom reading the DVD in there. I ejected it, and the reading sound went away. I turned everything on the car off, hit the llock button on the car, and there was still the sound of the fan on the back of the unit going. Is this normal? I took the unit out and put the regular radio back in, as I was worried about the battery draining if this isn't normal. I have a 90 day warranty on the unit so I may need to see about swapping it out for another one if it doesn't work out.

Thanks,

matt

To mount the antenna in the OEM location, you will need to pull back the entire dash assembly. You may be able to get creative so as not to require this. I've had my dash out for other reasons and can tell you it is a fair amount of work.

As for the question on the fan, yes this is normal. After a period of time this will stop.

In case you had not seen these yet, I've posted a few pics here...

The small square metal plate is part of the antenna assembly. It attaches to the whole aluminum frame structure of the dash.

There is always power to the various electrical components on the STS. When you open the door, the Nav begins a startup sequence, preparing for use.

That must have been what I heard then.

ddadler, I saw your post with the dash taken apart. Is that little mounting plate not immediately available when the forward most dash pad is removed?

No, it's not. I was rushing when I did mine because my friend was in a hurry and I needed his help to maneuvre it back into place. I took photos of everything except the dash... DOH! The dash extends all the way to the glass. The panel over/around the defrost vents merely snaps into the dash. There is no better access, unfortunately. When I first looked through the FSM at replacing the antenna (I thought mine was bad), it confirmed this is the procedure.

I found a few pictures I took. The dash was still in the car, but the top panel you're curious about has been removed. You'll see there is no access to the antenna.

So are you saying that you do replace the antenna just by removing that top dash panel? And then struggling to get it mounted? I've got plenty of time to finish this up, so if I have to struggle for an hour or two to get the antenna in that area, it's not a problem.

Also, how do you remove that top panel? I had the clips near the drivers seat all popped out, but then the panel would not move any further. I could see the clips by the dash, but cuouldn't figure out how to get the panel up.

Also, I took some pictures of the connectors I have that were connected to the factory CD player. And when I looked at the photos from the Nav Installation Thread, it looked like there were a lot more wires in the second connector where I only have one wire in it. What am I missing in this wire?

When I put a lock pick in, will I have the wire on the lock pick to tap into the vehicle speed sensor on the vehicle? The car currently locks out the function on the set up when I'm moving.

No, when I looked at the procedure in the FSM, it stated to remove the dash. My first hand experience confirmed this is necessary (sometimes the manual makes things more difficult than it really needs to be).

Unfortunately I don't have current access to wiring diagrams so I can't compare the two connectors for you. It might be well worth $20 spent to purchase a 3 day subscription to eSI (the GM Service Information documentation). This gives you the same information available to dealerships. You can do this at http://www.acdelcotds.com. You'll be able to view virtually all current GM vehicle documentation for every vehicle over the past 15+ years. In addition to all the connectors and schematics, it will provide instructions for any procedures you need to follow to do this work.

Someone else should be able to speak on your LockPick question. I don't have one and am not familiar with the product.

I plan to buy the service manual soon, but have dropped a bit of coin, so it will be another couple of weeks before I pick one up. I don't like to let the credit card get out of control, have to pay it off before I go crazy again :)

Either way, I'm installing the Nav because I wanted the touch screen. For my eight mile commute to work, I'm pretty sure I won't get lost :)

I understand. I tend to spend more money than I really should, or need to. But upgrades are nice so I just work a little more to support the habit :)

It doesn't sound like you'll get lost in your commute. But, it doesn't sound very different from my friends giving me a hard time over the rear heated seats I put in my other car. I rarely carry passengers but I explained that it's quite simple... It's not whether you "need" the option, it's about being able to say you have it ;)
