Same story on the interior roads of Chikmaglur too.
Having studied the map data of practically every provider, i have to conclude that google's is the best. Not sure what the data sources for others are, but a fat lot of the roads they show dont exist

Oh God! Even MMI is like that? I had similar experience with Satguide yesterday while driving from Manipal to Bangalore via Chikmaglur.

This was my first time with GPS on all the time. I had Garmin 260W running on Satguide maps. I had given my destination as Chikmaglur. My drive started with driving on what it called perduru road, which was in reality Karkala-udupi road or SH-25A (google thinks it is SH-65). As I turned left at Hiriadka, towards Perdur, it protested and asked me to continue straight on perdur road (or SH-25A in reality), which it wasn't. After that it decided that I was not on any known road until I hit Hebri. In fact I didn't see Perdur road when I passed through the town Perdur. At Hebri, GPS perdur road joined us back. About 3kms later, all maps vanished and the Germin said it can't navigate anymore. It didn't know any roads after that, not Agumbe, not Sringeri... It just behaved like an expensive compass, just telling me the direction and speed. While wife was continuously trashing the equipment, I wondered something could be wrong here. So I did restarted the Garmin and got the map back on. Now I was on Chikmaglur Hwy or New Hampshire 13. Confused? Well, it interpreted NH-13 as New Hampshire 13, one of the states of USA.

Incidently my history buff mind was thinking about the original 13 american colonies and NH was one of them. A GPS device with a historical sense of humour?

Thirteen Colonies - Wikipedia, the free encyclopedia

Every now and then, the device used to declare I am not on the road. I was going offroad for few Kms and join back the highway. Not an easy task in the Chickmaglur terrain, even with a GV. It become more accurate in the Chikmaglur city.

It again become completely clueless on Chickmaglur-Belur road, it asked me to continue into a huge lake while the real road veered to the left. The GPS road joined me back few Kms later as the road turned back after crossing the lake.

Upon entering Hassan, it asked me to turn right into a sewage canal, when I continued striaght, it re-calculated and asked me to turn right into a shop, and then again into a house. But I only turned when I found a road.

And yes, the road from NH-48 to Magadi, was safely put a Km away from where I was travelling. It kept goading me to get back on New Hampshire 48. The GPS become accurate only after across magadi town and remained accurate all the way home.

And I kept thinking, this is the difference between Satguide and MMI. The MMI would have been accurate outside Bangalore too. That is why MMI is 8 times more expensive than Satguide map for Garmin.

But now Amitoj says MMI is equally clueless outside Bangalore. Now what?

Hey Srini, COngrats. I will be getting my 265 W in a couple of weeks. Read that there is a discount going on for SatNav maps (990 ??) so wanted to buy one in advance. Which one should I get for the 265W, SD card or SD card with adapter? Thanks for your help.

CHeers!

Thanks Samurai. Reading the review of the maps by you and Amitoj It looks like the maps are good only for the intra-city commutes and pretty bad at inter-city connectivity. Looks like we will have to wait for a while before we get a reliable GPS provider.

When the maps are made that accurate, then that will actually count for something!

One of the early results of Satnav (as it was then) becoming popular at sea, was accidents caused by people trusting its accuracy. Actually, there was nothing wrong with its accuracy: what they forgot was that the sea charts had been surveyed long, long ago with compasses and sextants.
"Don't worry about that the rock: the Satnav says we are 200 meters away"... bang... glug, glug, glug... Help!

yup, "Europa" currently has the best road coverage in india, which is the map provider for Google.
Second best provider is "CE Info", used by yahoo india and MyMapIndia.

There are other less detailed map providers like "NavTeq"(for Nokia Maps) and "RoadsOfIndia" for SatNav.

Do anyone knows any symbian gps software which uses "Europa" maps?,if there is one it would be a killer app....till then Mgmaps all the way.

Ok so I just tried to buy the maps for the Garmin online and the transaction failed for some reason. Before I could figure it out, I get a call from the SatNav guys asking me if I needed assistance. Then they gave me an account number I should transfer the amount to and they will courier the card to me. They had the address I had filled as well as my email address from the form.
I am impressed.

All the gps maps are equally pathetic.

recently i went to a theme park called mayajaal just on the outskirts of chennai and my satnav showed me driving on the sea ( bay of bengal)!!.

It is not enough to make the satellites more accurate. Making a good map is always a good option. And MMI and SATNAV must keep updating it properly every now and then

Folks,

The real value of maps, I saw is in places which are alien. No point saying the map does not work,
on a place that you know. I do agree that they work everywhere. I have had good experience
with Satguide especially in by-passing places, on long drives.

At least they have not let me down till now! Also Satguide is good VFM.
But yes, VFM does NOT mean non-reliable. I am OK if it does not show a route.
But if it shows wrong data, then I am not OK.

I fully agree. In Australia, when we drove to Great Ocean Road Drive/Phillip Island/Balarat last year, my son-in-law's Tom Tom GPS got confused and misguided us many a times.

Hi everybody,

Am contemplating on procuring a PND for my car before my upcoming family trip to Sikkim. Would be grateful if I could get some guidance from users' experience about the following:

a) Which is the most recommended device (have short listed the MMI Roadpilot and LX 130)?

b) Comments on accuracy (especially from Kolkata to Sikkim, if anyone has used it on this route)

c) Updates issues

d) Any other helpful information

Thanks

@aparnesh
Not sure about the MMI Roadpilot. But the LX130 is pathetic. I had a look at it 5 - 6 months back and it looked like a cheap chinese device which kept hunting for the satellites for some time from a cold start.

Major highways are no problem for both MMI as well as Satnav maps. Problem comes only inside cities and some rural roads. So Kolkata to Gangtok shouldn't be a problem.
