Can ask simple question regarding GPS. New user here. Jus got my phone one week ago.

I have read on Tread 6 that Uncle Benny mention Sygic Aura. When i search in the market, there is Sygic GPS Navigation. Is this the same?

To use GPS, i need to download map and save to external SD card? Current i don't have any SD card. Means i can't use GPS navigation?

Is function same or similar to Garmin. I used my friend's garmin before so not sure if this phone work the same.

Sorry if i repeat this question. I read until tread V6 but no time to read the rest yet...Need to use the GPS on weekend since i m now in a new area...thx
