DeLorme software on Android or Windows 8 devices
DrAlloway
I already have DeLorme sfw and would like to integrate with tablet and GPS for riding my motorcycle cross-country.

I was thinking of buying a 10-inch tablet with WiFi and Bluetooth.
Buy GPS receiver that talks to tablet via Bluetooth.
DeLorme speaks Turn-by-Turn directions via Bluetooth to my helmet Headset.
? this idea will work ? right ?

I am running DeLorme on my Win 7 laptop - so I know that works.

Does DeLorme run on Windows 8 tablets/computers?
Does DeLorme run on Android tablets/devices (like 10-inch tablet)?

Alternatively some tablets come with A-GPS (are those any good - like accuracies to 3 meters ??)

If my basic idea is feasible, then I can buy whatever components will really work - but - I can't afford to waste money on devices that won't integrate.

Bluetooth GPS devices are available and quite good. I'm sure any Windows 8 device with Bluetooth could talk to your headset.

Delorme should run fine on a Windows 8 Pro tablet (NOT RT) or computer but I don't think they offer an Android version.

As far as I know AGPS does not offer better accuracy; just a method of obtaining a quicker initial fix via an internet connection to the latest location data. In most warm start circumstances, you would not notice a difference at all.

A good GPS takes a fix something like 10 times a second (IIRC)
PLUS Turn-by-Turn instructions could overload a Bluetooth connection ??

I don't know but it would be nice to know before I drop big $$.

Same with DeLorme on Win 8. I think it should run fine also, but does anybody know?

I wasn't suggesting that A-GPS is better than regular GPS - rather - that some cheapo chip set in a tablet might yield accuracies like 50 meters, unlike the quality chips in dedicated GPS recievers than can achieve 3 meters. I am asking if anybody knows if any or some of the GPS chips in tablets have decent accuracy??

The instructions are generated by the Delorme or other mapping software on your computer, not the GPS. The amount of data transferred from the GPS to the computer is miniscule - much less than Bluetooth would have to cope with transferring sound to your headset!

The problems associated with internal GPS chips in a tablet or laptop are not necessarily controlled by their quality. They are closer to electronically noisy components and you have less options in the placement of the antenna. Standalone GPS devices are virtually always superior because of this. You will pay for a good Bluetooth GPS though!

Thanks

I would assume the GPS antenna in a tablet would be a design compromise.
Plus how would I position it for best reception and still see the screen.

I have an HP tx2000 running Windows 8 Pro and tried Street Atlas 2011 on it. You didn't specify which Delorme product you were discussing and this is the latest I have.

It is working with a Bluetooth iTrek M7 but I also tested it with a BT Garmin 10x as those are 2 of the Bluetooth GPS devices I have. Determining which COM port the BT GPS is using on Win8 seems a little tricky but not impossible.

Excellent - very glad to hear that.

I have both Topo 8 and Street 2012.

Have you tried Street sending turn-by-turn to a BT headset ?
tcassidy
I didn't try Topo 8 as it does not include Canadian data.

No! Although I have several BT sound devices, it would require me to actually travel with the device to properly test that. I did notice that Win 8 natively supports headset Bluetooth protocols where Win7 didn't. You had to use separate software. Still, that might be related to the BT hardware this laptop has.

As the turn by turn instructions are just a sound it depends on the laptop sound being able to be routed to your headset. I know it works with at least one of my sound devices but you might want to test the laptop/ slate you are considering with your headset!!

Thanks again.

The market for Win 8 on tablets (and small laptops that convert into tablets) is new
and rapidly changing -- so I am going to keep investigating while they work the bugs out.

However, I have to buy and integrate components in March as I have a 1,500 mile motorcycle trip starting April 3 which would be a great time to test my systems integration.

I am not a motorcycle person but the problems I see are;

1.space - where do you put a 10" tablet on a motorcycle

2. brightness - 300 or so nits won't cut it in sunlight especially with a reflective screen which seems the popular arrangement.

3. Mounting - how do you attach it in a reasonable way.

Maybe its just me but I have these problems in a full size truck!! You really should consider something specifically designed for a bike and relegate your SA and Topo Delorme products to a more suitable environment (in my limited opinion!!).

In that case, forget about Windows 8. Get a last generation Windows 7 tablet as it does everything needed and is cheaper. Windows 8 adds nothing you can use that I can see.

A built-in GPS antenna may not be as good as the latest external antennas available but not due to design compromises, rather the chip. All the latest smart phones have GPS chips in them and they work pretty well so I don't think you need worry about 'design compromises.' I have a UMPC (much smaller than a laptop) with a built-in GPS antenna that works as well as an external antenna with a the equivalent chip regardless of position, even under the car's metal roof. Oh, yeah, Windows XP, too.
tcassidy
Sorry SF, but I don't agree. I know your UMPC has a SirfStar III chip as does my ASUS UMPC ( an excellent chip even if the implementation power wise is less than stellar). However, what I suspect these days is cheaper chips are used to reduce cost and size. Just look at where MS is going with their later GPS devices.
