Bottomline is that the app is good, but if you want to calculate 0-100 times you'll need way better GPS modules than those that come embedded on a mobile.
Well with most mobiles having a 1HZ GPS update, no wonder you can't get very accurate GPS based timing not to talk of lesser satellites they lock in, and obstructions like tall trees/buildings etc. So, 0-100 does not make sense on the phone... Accelerometer based stuff is more accurate (relatively) but you need smooth roads etc

@NetfreakBombay, thanks for pointing it out. Yes, maps for Garmin happened later than when the iNav's came out. Actually, the iNav WF navigation software and adaptation to mapmyindia maps is pretty crappy, I am sure Garmin XT with the new mapmyindia maps will be 10times better. I still keep using mgmaps simultaneously with the iNav WF - the reroute on the iNav is fast and its best feature...

oh. Netfreak had said that cell phone level gps modules work at 5hz..

And how does a accelerometer gather 0-100 times ??

Check out the dynolicious thread on tbhp. It works on iphone. When I searched many months before, I did not find a accelerometer based app for S60, though N95 and N82 have a 3d accelerometer just like the iphone ...

Your question itself is unclear, but you would need both Map Software and GPS Receiver.

Perhaps @Vinod_AirNav meant whether he should buy a dedicated GPS unit (PND) or software for a phone?

@vinod, the experiences and cost are completely different. Both come with maps. A dedicated GPS device has a much bigger screen, is costlier but doesn't do anything other than navigation (discount the odd unit's ability to show pics or videos). These units always have the GPS receiver built in.

Navigation software for a phone (there are more available for WiMo phones, but even Symbian phones are not far behind) is cheaper, but works on a smaller screen and is limited by a relatively slower processor on the phone. If you don't have GPS in your phone, you will need to buy a matchbox-sized GPS receiver which costs around 3K.

Garmin, Sat Guide and MapMyIndia have both dedicated units as well as software for phones available. It is also possible to buy a generic PND (Personal Navigation Device, usually comes without the navigation software) and load the navigation software.

Not sure who in Kochi stocks Garmin - maybe you can enquire at large shops like eZone or Croma if they have a branch there. A friend got a Garmin 215 for 17K in Bangalore.

Please let me know the pros and cons of using the Nokia 5800 as a GPS unit. I am considering it since its cost is said to have come down to 13-14K.

Pros
Good gps unit,fast locking when AGPS is enabled,don't need to carry two units

Cons.
Some programs may have compatibility problems with its touch screen(not sure),battery will only last 4hrs if gps is continuously used, so car mobile charger is needed.

Software you can use with 5800
MGMaps=free,can use both google map and yahoo maps
Mapmyindia=Rs3500,same as yahoo map coverage,voice navigation

I am using n82+mgmaps only problem is no voice navigation.

@splitsecond, you could use Garmin or Route66 on the Nokia if you want voice-guided navigation. Not sure of the cost.

Even the Nokia maps are good in the cities (better than mgmaps, since it is road-oriented), though voice-guided navigation is a paid Nokia service.

Unless you have an unlimited data plan don't go for these internal gps units on cell phones. The a-gps feature requires a constant gprs connection and if you don't have an unlimited plan things won't end up good. Other than that not only are they slow to get a satellite lock, they'll have precision problems at higher speeds as well. But if you still want them then you could use mgmaps application and store maps on your cell. I've posted an article about that here ₪ In Focus: Symbian S60 3rd and 5th Edition ₪ There'll be a link either in "tricks and tweaks" or in "nseries stuff" on the horizontal menu. I can't post the exact address because i'm mobile right now.

Vodafone has a good data plan which i use - 50mb per month for 95rs. It was an unlimited offer until last month.

@DerAlte I'm not sure of Nokia maps' details for cities in Kerala, the last time i tried it was pathetic. I'd prefer the hybrid view of google maps anytime for places here. But it's a different story for major areas like Kochi though.

Cons:
  1. Nokia maps is expensive as it is not priced as per Indian market.
  2. MapmyIndia maps are available on Nokia (Available, but costs 7k).
Pros:
  1. Garmin Mobile XT runs fine with touchscreen on 5800
  2. Satguide maps for Gamin costs just 2k.
  3. Sports tracker is excellent for logging your tracks and uploading it to net.

Unlimited data plan for my BSNL costs only Rs.199/- per month. But speed is pathetic here.

GPRS is NOT an issue at all.

GPRS is only required when you are starting the navigation. It helps is speeding up "fix", I.e. the time it takes for GPS to calculate current position.

And A-GPS can be turned off. In that case, GPRS would not be required.
