GPS CF Vs BT

andrems · Posted: Sat Oct 23, 2004 12:55 am Post subject: GPS CF Vs BT

Hi.

I'm new in this GPS and PDA business. I'm planning to buy the new Dell X50v PDA since it has a good processor, CF and SDIO slot and a VGA display which I think it's best for viewing, specially while driving.

But I don't know whether I buy a CF or a BT GPS. I want to use it inside a car, and on foot also.
-CF is good because doesn't need to recharge battery, and it can be always attached to the PDA, but I doubt if will work on my shielded windscreen. (I saw the SDIO Globalsat 501 which has very good sensibility, I wonder if it's worth it).
-BT makes PDA lighter and can be put anywhere in car, but also needs recharging and I don't think it's the best solution for a walk.

Can you experienced users give me some advice on this?

Thanks,

Andre.

as above if you go for say a navman 4400 or can find an old 4100 then the battery life is quoted at around 30 hours

Hi. Thanks for the hints. But I have these questions that worry me.

I believe that BT is not very suitable for a walk, because you have to put the GPS somewhere, maybe in your pocket (I don't know if reduces the quality of GPS reception), since it can't be attached to the PDA. Sometimes it isn't very practical to carry the BT Gps around when you're on foot, and already carrying the PDA in your hands.

And the battery issue concerns me because suppose that I'm going to a long car ride, and that BT gps has low battery left but still enough to not indicate the battery low warning. In this case I don't have the slightest idea how's the battery leve. It's probable that it will run out during the trip, and can't be connected to the car lighter because the PDA it's already there. Right? With BT I had to recharge it everytime before I use it. So, with the CF I don't have to worry about these things.

Waiting for your comments, and thanks.

Ever heard of a Y-cable? You can use that to power both the PDA and the BT receiver in the car, and you can always be confident that the BT receiver is fully charged when you take it out of the car.

Some mounts (like the Seidio G2500) also offere a power-passthrough where you can connect BT receiveres directly.

The Y-cable is a solution. But since my windscreen is shielded, I have to put the BT in the back, so in practice I would get a wired BT from the front of the car to the back (it would be a waste of money for a wireless product)

And still nobody answered me about walking on foot with a BT GPS. Is it ok being in a pocket?

My car has a cigarette lighter socket in the trunk...

Yes, it's ok to have the BT receiver in the pocket. Of course it's better when that pocket is further up, for example a shirt pocket or a pocket in a shoulder strap.

Ok. I'm getting conviced by a BT receiver. Do you recommend anyone special, or they're all pretty much the same?

Btw, when do you think it's best to use CF?

Thanks.

Ok.

Last questions from this annoying newbie.

1- What drains the PPC battery quicker? A CF GPS card, or the BT turned on?

2- In what situations it's more recommended the use of CF instead of BT?

3- Between Fortuna, Emtac, Navman and Pretec BT receivers, what you should choose and why?

And thank you for all your patience.

Andre.

I would also like to comment that CF GPS can have issues with the CF Slot in your PPC. I had terrible problems with a Holux CF with my Pocket LOOX, luckily Holux told me about the issue and so I bought a wired version.

The point about wanting to use it for walking and how long the battery lasts in a PPC. I don't know how long you are looking at going for a walk but 6 hours should be sufficient for some of the most exillirating walks I would have thought. Then you can charge your PPC when you get back to civilisation.

Hello,

I use a 2210 with a Globalsat CF GPS & have had no problems over the past 12 months, I did try a freinds bluetooth GPS & had nothing but problems (loosing sync with the PPC). Personally I dont think that bluetooth is good enough yet to completely replace a direct coneection, those out there wirh BT GPS can you honestly say it does not loose sync with the PPC a few times over a 4 hour period?

That said this is my personal opinion, others I am sure will think differntly.

Whatever you choose just remember nothing is perfect!
