Hi guys!

I wanted to get the navigation system for the 8, but thought that $2000 is a way too much to pay (I could build a 3 gig P4 gaming rig for much less than that!). Instead, I'm thinking of getting an aftermarket , portable nav system and just wondering if any of you have had experience with either of these two models:

Garmin StreetPilot III:
StreetPilot III

Navman iCN630:
iCN630

I like the Navman over the Garmin b/c it's newer & can be attached to your windshield & dash (I think it's perfect position would be directly under the rearview mirror). Also, it can be found online for under $800.

Opinions?

I believe a tray option exists for the center dash to allow mounting of a third party LCD panel or navigation system:

About two weeks ago I purchased the Garmin StreetPilot III from eCost.com for $735. There is also a $100 rebate from Garmin. I decided to by a portable unit rather than the builtin Nav unit so that my wife and I could use it in our cars as needed. It is not something I would need in my car all the time.

I looked at both the Navman and Garmin products. Here are some of my pros/cons (from memory):

Navman: Pros
- small size
- built in speaker
- Has WAAS support (supposedly improved accuracy)
- The screen supports 1000's of colors but who cares on a map?

Navman: Cons:
- More expensive than the Garmin
- Harder to find, I never saw one "in-the-flesh"
- I'm not sure if you can attach an external antenna
- Has some built in memory but does not come with any removable memory

Garmin Pros:
- Widely available
- In my use, it has worked great for me. I love the voice directions. They are clear and informative.
- Comes with all accessories. The bean-bag stand works very well.
- The maps are very clear and easy to read while driving.

Garmin Cons:
- The speaker is not built in to the unit. It is part of the power cable. That is a little klunky.
- The City Navigator CD ROM of streets is a little out of date. I wish Garmin would update more often.
- The main unit is a little clunky and heavy, but it is well built.


By the way the most recent issue of Consumer Reports looks at automotive navigation systems. The StreetPilot was top rated, but the Navman was not mentioned since it is so new.

When you are considering going the handheld aftermarket route instead of factory integrated, you have to consider the following (some might be tolerable, they are merely considerations):

-A portable sticking out in the car will be a much easier target for a thief, so you have to constantly put the portable away if you want protection (inconvenient, and people tend not to do that).

-In most cases, a portable is not mounted as securely, and can become airborne in an accident.

-In most cases, the screen on the portable will be smaller, therefore harder to read, especially when you are driving, and the less time you spend focusing on the nav the better.

-DVD-ROM based in-dash systems are going to have more features than portable CD-ROM based systems.

-At the same time, due to battery consumption considerations, portable units will normally not have as much processing power (so they will either be slower, and/or have less features).

-In most cases, portable systems will not be 3d, as is the factory model.

-99.9% of the time, the controls of the factory nav will be easier to access and operate while driving than a portable unit, especially if the steering wheel based controls in the RX8 control some aspects of the factory NAV (such as volume).

-Portable units mounted in places like the windshield or front of the dash will block vision, get hot in the sun, and will be harder to read in the sunlight. Factory units are located in optimum locations for that.

-Battery consumption and/or cig lighter wires are less convenient than an indash configuration.

That's not to say that a portable unit is crap, and won't meet some people's needs. But you're going to have a hard time getting a portable system that is cheaper, yet has all of the features and conveniences of the built-in unit. The reason why it is $2k, is because they decided on a higher end unit, and because it's integrated into the car.

Thx to everyone for their input! Much appreciated!!!

Some points:
1 - if I did get a portable, I'd take it with me and not leave it in the car. The Navman has a bigger screen and yet smaller than the Garmin (also, the Navman has voice as well)
2 - I think the Garmin look way more durable
3 - I like the look of that dash tray!
4 - The Navman comes with the same if not more accessories as the Garmin and it also includes a windshield sucker mount.
5 - The Garmin can be battery powered, while the Navman is onlypowered by the cig lighter. Not sure if I like the idea of a power cable hanging down all the time.
6 - I now understand the differences between the DVD vs the CD-ROM/portable versions. Basically, I guess it breaks down to this: DVD - more expensive but has way more features; Portable - less expensive, less features but (as the name suggests) portable

More questions:
1 - Do you think that the Mazda Nav system can be installed by the dealer later? I figure that if this was possible, it cost a hella lot b/c they'd have to tear your car apart to install it. (Note: it's not listed in the new dealer's RX-8 accessory pamphlet)
2 - Doesn't the Garmin's beanbag move or shift when you turn?

Someone previously posted that the factory NAV cannot be added at a latter time. As to the Garmin beanbag moving during driving, I can speak from personal experience that it does not, at least under normal driving conditions.

While the screen size is smaller than the factory system I find the Garmin system easy to read and it does not block your vision while driving.

- The Garmin beanbag mount is very stable. I've never had it move. However, it is certainly not as safe as an indash system. It will be a projectile (probably through the windshield) in a head on collision. Garmin also provides a stick-on mount too.

- Does anyone know what features the Mazda Nav has that are not in a portable system? What "way more features" does it have?

- As I alluded too previously, a huge advantage over the Mazda Nav is I can pick it up an put it in my wife's minivan for use on those long trips. We don't need to buy two built in systems. It's not like I use the navigation system everyday nor is it likely that both of us would need navigation assistance on the same day.

- The Garmin does not block my view. It is fairly short, but of course it depends on your seating position and the location on the dash you place it. Both mounts provide side-to-side and tilt adjustments. I have never had trouble viewing the screen in daylight.

If I understand correctly, the main selling points of the DVD nav are:
1 - DVD-rom data storage. No need to transfer maps from your PC to the nav system.
2 - Factory installed. Controls, LCD screen and internal antenna mounts.
3 - Larger screen
4 - Possible 3-D navigation software. I saw that Japanese commercial for the Mazda 3-D nav, but not sure this will be included in the US.

kwolfman

What do you mean by 3-D Navigation? The Garmin has a status screen which shows which satellites are currently being received and their lock-on status. At the top of the display it sometimes says 2D navigation, but if four or more satellites are locked on, they it says 3D Navigation. I presume that is what you mean?

There was a reference in another thread that the Japan Nav system for the 8's gave a 3d map perspective (buildings and such) when you zoomed in. Others questioned this feature for our model because of the amount of information it would have to hold given the countries difference in size & amount of cities.. etc..

Look as JSG comments about 3d-Nav on Japanese models.

We'll have to see the cars before we can make that decision. Since this car is being built with NAV, you will be able to put it in afterwards. Whether it's feasible or not depends on:

-How much the replacement parts will cost, especially the electronics. Sometimes, replacement factory radios are beaucoup expensive, and they get more and more so when the models change.

-How many items need to be replaced. For example, to put a factory cruise control on my parents new Focus wagon (they were told that the manual wagons don't come with cruise from the factory... I don't know why), you need to replace items like the steering wheel. For the nav in the RX8, it might be as extreme as having to completely replace the dashboard for the nav monitor, and it might be as extreme as having to replace the console to accomodate the nav controls, in addition to the nav hardware itself.

And even if just getting the parts to put it in is reasonable, some dealerships might not want to do that type of "custom" thing. Again, my parents ran into that with adding cruise control on the Focus, even though there is a kit available from Ford for just that.

So, unfortunately for the pre-order folks, there's no way to really tell how difficult it would be to put the factory nav in after the fact. Especially since the dealerships haven't even gotten their basic training on the car yet.

Wow! Good points!

From what I've just seen on Mazda web site, the Nav system's three antennas are placed in the roof. I think that would involve too much work (and cost) to justify nav as being a dealer installed option.

Oh well, back to the original two....

One more thing, nav is on the bottom of my list of accessories to get. Here's my list in order of (future) purchase:
1 - Spare tire kit
2 - MiniDisc player
3 - Spoiler
4 - Winter tires & rims
5 - Splash guards
6 - Aluminum door sills
7 - Aluminum air vent bezels
8 - Nav system

no, what that means is that because of the number of satelites, it is able to record movement in 3 dimensions.
This gets kind of wierd because the surface of the earth is 2D, not 3D like the earth itself. With the third dimension it is probably measuring hieght/depth (like going up a hill) which would change the distance traveled in 2D (ie, instead of being at house 20 going up a hill, youd be a 25, though your only at house 20, you get that extra distance from moving upwards, measuring in 3d would null this, though i dont think it would be even measured in a 2d scan....) or SOMETHIGN, dont really know what it means, but that is probably it.

A 3D NAV system can display your distance above sea level where a 2D cannot. You need three satellites to lock in you coordinates but you need to lock on to four satellites to calculate your distance above sea level. I presently have a Garmin StreetPilot III mobile navigation system, which is 3D.

there is a cheaper (OK more ghetto) way of doing it if you have a PDA or laptop.

If you go to http://www.destinator1.com/ you can buy a GPS receiver and navigation maps for around $300.

Good - The GPS receiver is pretty good quality (12 channel) and the maps are in a 3D view so its easy to use. Also, its completely portable and can be changed from car to car or even taken along hiking/biking/hunting. Oh yea, and its pretty cheap!

Bad - Well, you have to rig up a way of mounting it. The screen will only be the size of your PDA (or laptop). Also, probably hard to use while driving (although it does thankfully recalculate routes automatically if you make a wrong turn) so its best used with a navigator in the passenger seat.
