Drove in my friend's V yesterday. Great car, I love it, but one thing that bugged the heck out of me was his navigation unit. Every couple of seconds you could hear the CD "spinning up", just like the sound in a computer when you play a CD. It was loud, and I could hear it from the back seat even. I've never HEARD of that happening before, and I didn't know you had to have the navigation CD in the drive in order to use the GPS....... do you? He said you do, and I called him on it and called the Cadillac dealership, but the Cadillac dealership agreed with him.

I thought the navigation CD was only to load the maps, firmware, or whatever else, and then you were done with it.

Is it true you need to have the Nav CD in the drive whenever you want to use the GPS!? What if you want to watch a DVD, do you have to take the NavCD out, pop in a DVD.... and then what if you want to switch back to GPS for a minute... do you have to swap the disks again?

Doesn't make sense guys :-/ I've never heard of a car's GPS needing to have a CD in the drive when you want to use it.

All factory NAV systems require a DVD to read the map data off of - the onboard GPS unit simply tells the system where to place you on the map.

If you drive with a DVD movie playing in the Nav screen, be prepared for a ticket as it violates Federal Law. It's a good law too, because the only thing you should be watching while driving is the road.

If you can hear the nav while driving then you need a new exhaust or the whine of a maggie under the hood :)

The map dvd needs to be in the drive and is accessed by the nav as you drive. The only systems I know of that let you download the maps into the nav or put it on some kind of memory stick are aftermarket units and those can't usually hold the entire US map at once.

Like Tony said, the system does not have the capability to use the nav while playing a dvd movie since they use the same drive and like he said, it's against federal law to have a movie player that can be viewed by the driver.

yeah that's true about not watching movies while you drive, good point.

but it still bugs me about hearing the SOUND of the CD spinning up and down while driving.

so all cars that come with GPS (acuras, hondas, etc.) all have the CD in the drive!?

Mine makes the same sound. I never noticed until last week while at a stop light with no music on. Works fine, but it can be annoying. Just turn on some music and get on down the road.
On a side note.....of course it's illegal to play a DVD while driving. Now if all you that said that have never hit 80+ mph in your V, then may he take your advice seriously. If you've been above 80+ mph, stop calling the kettle black.

That's the most ridiculous argument I've ever heard. I'd much rather have someone coming toward me at 80mph and watching the road than someone doing 45mph and staring at Jessica Alba's ass on their Nav screen.

It is annoying, but dealable. I think its my phone on vibration in the cup holder. Gets me everytime. Driving and watching is dangerous. I only watch stuff I already know or watched before. Definately helped me get from Jerz to Florida and back.

so my question is do other cars have this problem?

I mean no offense, really, i love this car, and i can't wait to get mine, but i'm wondering if i'm going to end up keeping it for that long, it seems the problems and quirks are just insane. And before you start flaming me just because you own and love your V, just think logically... this is a hell of a lot of money to drop into a car that has more problems than I can name off on the fingers on my hands. Does the STS-V navigation system make a noise?

I would rather watch Alba's ass than look at you on the road....

When I get in the car and start it up I hear the DVD being accessed, a few spins/reads, but then that's all, and I never hear it again. Now that could be because once I start moving I usually have the radio on, windows down, and/or hear the sound of my car's engine and exhaust, road noise from the tires, etc. But I've never even given it a second thought.


S.D. all I see is :aniredx:

I would think that it's not suppose to make alot of noise. Mine doesn't make any noise at all. Maybe a few "searching/reading" noise at start up, but that is it.
