I’m using a Sony Ericson C702. I’m looking for an application which allows my mobile phone to navigate using it’s built in GPS without the use of GPRS service to reduce cost. Can someone pleade help me?

I have recently bought a satnav/GPS and found that the speed recorded on the machine differs from my cars speedometer. Which one is more accurate? Is this normal?

The features I like are voice instructions, 3D map view etc. My budge it 100 dollars. Which GPS should I buy. Sony, TomTom or Garmin?

The speedo on my bike doesn’t work, so I removed it and I’m thinking I can just get a GPS that shows my speed. Smaller is better since I just need the speed and not the map and directions. Anyone have suggestions?

I am moving from Cincy, OH to Aurora, CO and would like to purchase a GPS system. There are so many out there; it’s hard to decide which is best for my needs.
