How do I recalibrate the GPS?

[wheeling]

Go to the Telenav website and check for yourself, it is not the antena or GPS interference, it is the data. Input a 2 year old address, it directs you to a location half town away. A 10 year old address, across the street. It is the source data that Telenav use really bad. They have the new highway update, but teh details are wrong. May not not be Ford fault, but they should check before they buy, like we do, right? Just hope that thic can be correct in a later model year.

Wrong. We didn't check before we bought. If we had, we wouldn't have bought! LOL!

Wow, you guys are right Telenav's maps are way off... Thats stupid.

I was cleaning out my glovebox the other day and decided I could safely through away the plastic case which held the Telenav data SD card. While looking at it I noticed that it is labeled as Version A1, which I am going to assume means that it is the very first data set....

A quick Google and I see that Telenav wants $300 for an update! (http://www.pocket-lint.com/news/40746/myford-touch-telenav-satnav-hands-on) Gee, $300 for an update or $150 for an awesome TomTom or something similar? Ford and TeleNav should be ashamed if that is the true price. We should be able to download the data onto our SD card via the internet for free.


So- does anyone have a newer version of the data?

Garmin is offering free lifetime updates on some of their models. I think that may also apply to other brands of GPS.

Just checked the Telanav web site. Our map version is the latest. There is no update available yet.
Someone posted updated map available for 300.00
My Magellan update in 2010 cost 39.99. They only update maps every two years. I believe they use Navteq.
Just took a 130 mile trip yesterday. 4 stops. Ex Nav was right on the money.
I have had only minimal problems.
Guess I'am a lucky one.

The problem is not the map data, I think, it has all the latest update, at leaset in my area, but the problem is the way it does the search, sending you to the wrong place. It is dead on for you in one area, that's great. Next time it may send you do a deadly place, that will be trouble. This GPS is not reliabe at all.

In its web site, I located the address on the map, type it in, and it send me to a location half town away, what a joke!

My NAV is of by 200 feet. But the biggest complaint is the info is at least 4 years old and maybe more. My neighborhood of 400+ homes was built in 2006 and my street is not even on the map. This calls in to question other locations as well. I called Ford and they said there was no update. I told them I should receive an up to date system for the expensive vehicle I just took delivery on less than a month ago. I told them that Ford should set the vender stright and demand current maps be supplied with new vehicles. The customer service rep said she would note the complaint and escalate it. We shall see what happens.....This is bull!

My street was built in 2001 and it doesn't exist with telenav or any tomtom. It does exist with farming.

OK, I thought that Magellan and Tom Tom also use the Telenav data. Is that correct? Any time I have someone pick me up using a Magellan or Tom Tom, they can not find my house because the numbering system for the street is reverse order. That is, actual house numbers from low to high begin on the North end of the street and progress to the South end of the street. Telenav lists these from high to low. That is the error I see in Ford, Magellan and Tom Tom. I verified my street by entering several locations as destinations using the map.
- Can those of you with a Tom Tom or Magellan check to see if that type of house numbering error is an issue?

 

[baxterdown]

Jazny, that is the exact same problem I have with my vacation home. The street is U shaped and Telenav has the house numbers backwards effectively putting our house on the wrong street.

Wow, telenav's data does suck. I tested about a dozen different addresses I know and it got less than 50% of them correct. They were off by 1 to 4 houses. This is just north of Houston too, not in the middle of nowhere, and none of the addresses were newer than 5 years, with some pushing 40 years. I was surprised (and disappointed!).

 

[GWA1]

Magellan is Navteq. Don't know about Tom Tom. I've had my Magellan for 4 years. It's never steered me wrong and has been quite accurate.

GPS / possible to recalibrate by myself / f.ex. with Forscan or other tools ?

I am living in Germany / need to recalibrate the GPS (or calibrate it once)...

 

[peterk9]

I've moved your thread to this existing thread. According to an early post, it has to be done by the dealer so you may be able to do it with Forscan.
BTW, I didn't notice before but do you have both a 2013 and 2014 Sport?

bump...???????
It was here in this forum that "someone" explained me that in US (US) the 2014 is really a 2013 produced...mine is produced in 09 2013 it means it is a """2014""" model...nice, very nice......but not constructive !? And: Ford Germany will NOT talk with Ford US...very ""yesterday"" for me !
BTW: sorry for my English...worked for the American Forces in Berlin, but (too) many years ago......

But: Thanks, I have to pay for Forscan now...hope it helps !

It is either a 2013 or 2014 Explorer. It doesn't matter when it was built. What was it advertised as being when you bought it? How was it registered?
Good luck with Forscan. Perhaps you should check with some of the Forscan guys to see if it is even possible before buying it.

You can not write calibrations (firmware) with Forscan. There is no user calibration of the GPS module either.

 

[Schimi]

you can only reset the GPS module.... maybe it´s enough....

In general there are 3 different things which can affect the "accuracy" of an address on the map

1) GPS Accuracy

This can depend on a few different things:
a) What chip you have in the GPS
b) # of channels supported by the chip
c) # of satellites that are "locked in" at time of reading
d) antenna used (ability to pick up more channels under worse conditions)
e) how many satellites are actually available in the sky where you are right now.. this varies all the time based on location and time (https://in-the-sky.org/satmap_worldmap.php)



2) Map Accuracy (General)
a) are the GPS locations the same in real life as on the map? (in Toronto, when software is not doing an auto correct, I've seen this off by about 8-10 meters some times on older software. Newer software should account for this)
b) each map company will be slightly different.

3) Address Look up accuracy
a) not all addresses in the map are correct. some can be off by almost 200 yards for rural areas


The best way to check a few of these is with a modern cell phone (Eg. android) which have access to many GPS tools to check and compare to the car.
