Re: Using Ipod Touch 4G as GPS
can i hook my nuvi up to my ipad?
I don't think so. The iPad has only the Apple proprietary input...no regular USB input. That and the fact that the Nuvi is intended to be a stand alone unit, I highly doubt there would be a straight forward way to get the GPS data from a Nuvi to an iPad in a manner tha it could be useful.
If your iPad is the 3G model you don't need an external GPS antenna. Just get the navigation app of your choice. If it is the Wi-Fi version then I'm not sure what is available to allow you to use it for navigation outside of Wi-Fi service areas.
It's interesting to me that you ask about a nuvi.
I bought a nuvi 500 last year for some pretty simple reasons. I wanted a small, inexpensive GPS for use in the car, boat, hiking or otherwise. The nuvi 500 was the most compact unit that promised all of these things. It is waterproof and has the capability to use the Garmin BlueCharts. The street navigation is standard fare for Garmin.
It is a fine little GPS and I use it in the car often. That said, one of the main reasons I decided to get an iPhone was that to get the charts I wanted for the Garmin it would have cost me about $250. That as compared to the Navionics apps available for the iPhone for around $10 each or $20 for the 2 areas I wanted. That was enough to convince me, then when you compare the functionality (or lack of functionality) of the nuvi to the Navionics apps and the rest of what you get with the iPhone, it was almost impossible for me to spend the money on the Garmin charts.
All the shortcomings of the iPhone mentioned above are true. However, in my opinion for someone on a budget that is essentially a fare weather boater anyways, it sure seems to work really well.
If you need to rely on a GPS device for your safety on a regular basis, then you likely will already have an appropriate GPS setup that fits your needs.
For the rest of us, if the only concern is the occasional threat of getting caught out in foul weather, a GPS shouldn't the decided factor as to whether it is safe to navigate or not. If it isn't safe, it isn't safe. In some cases a GPS of any sort will provide the guidance needed to get out of an unexpected situation. I guess, I'd rather have my iPhone than nothing.
