Hello;
I really would like to understand the difference between Car GPS and Trecking GPS. Are they similar?
I mean here from the point of syncing with satellites. I saw some trecking GPS that sync with 12 ( 12 channels). Does that mean that they are more sensitive than Car GPS?
Is it possible to use car GPS for trecking
Or are there GPS that can be used for both applications at the same time, and may be also for sailing, let's say
If they are identical hardware-wise, does that mean one can use maps files for cars on a trecking GPS, or vice-versa?
Thank you in advance.
I think the main difference is the power source and the software that is loaded. Car systems will be set up to use 12VDC, and typically be hard-mounted into the car. Trekking (portable) models will be battery operated, so voltage would be anywhere from 3-9VDC. Since a person will have to carry it, the portable GPS will typically be smaller and lighter.
Regarding software, Car units will be more likely to have better information on roads, addresses, attractions etc while the hiking model will feature land features etc.
All the GPS units I have seen use as many satellites as possible. It needs at least 3 to pinpoint where you are, the more satellites it 'sees', the more accurate it will be.
You can you a car GPS for hiking, but you will need to bring a 12VDC power supply... and car batteries are pretty heavy ; )
A better application would be to get a portable model and use that in your car, however I don't think the hiking models typically give you turn by turn instructions.
Hope that helps.
I am planning a road trip and I am horrible w/ directions. I am considering buying a GPS system for my car since we are driving from Wisconsin to New York City. Any suggestions?
If you only need it short term, you have a number of options. Do you have a friend you could borrow one from? Consider renting a car and getting the satellite thing with it.
But, consider this: you may already have almost everything you need. Many cell phones are satellite friendly. Most directions sites (I use mapquest.com) have an application you can download to your phone, and then 'send' your phone the directions from mapquest. Voila! It now has the capability to adjust for you on the fly. Goto your directional website of choice and see what hardware they support. (If they don't support your model of phone, try another site)
A seasoned traveler with a decent directional ability, I get my directions from the site, and used to print them. Now, I just save the web page to my laptop (usually the printer friendly version) and have it open on the seat next to me.
Drive safe!
I'm trying to decide whether to purchase the blackberry 8120 (which has wifi) or wait for the 8130 (GPS)?
What is the difference though? I am aware what wifi is but what exactly does GPS do?
Thanks alot.
wifi is wireless connection you can connect to wifi hotspots or other peoples computers some though reqire permission gps is global positioned sattelite which is for navigation and then there is gprs which is general radio packet data

My GPS started copping an attitude with me because it was on PMS. Luckily I captured it on tape
