Blurb on taxis would be more appropriate in taxicab or mobile data terminal.

Contributions regarding mobile phones gps navigation system[edit]

I'd like to contibute to this subject, I work for LocatioNet who makes Can I do it by myself or is it inappropriate? Thanks. Yoavf 07:41, 15 April 2007 (UTC)

see TomTom and Garmin for examples. remember to use a neutral informative format. Stephen Charles Thompson (talk) 06:32, 6 June 2008 (UTC)


There seems to be too much emphasis on CARiN, which is a proprietary map database format. None of its inner structure or methodology is discussed, so the treatment of it has limited value. Roesser 16:28, 5 August 2007 (UTC)

DIY GPS receiver[edit]

GPS-receivers can also be build yourself. Please take a look at DIY GPS receiver and perhaps include in the article. —Preceding unsigned comment added by (talk) 16:23, 9 October 2007 (UTC)

Better picture?[edit]

Who cares if it's in a taxi, let alone in Kyoto? We should take a picture of a satnav. Currently if readers don't already know what it looks like they would be excused for not being able to figure it out. Thanks. (talk) 19:21, 9 December 2007 (UTC)

Dead Reckoning on Portable GPS Units (Dispute)[edit]

Resolved: Error addressed in dead reckoning portion of portable GPS units

Medic48 Medic48 (talk) 03:28, 26 January 2008 (UTC)

This part of the article indicates that portable GPS units do not have dead reckoning available, however in the TomTom 920, it has an EPS module that uses dead reckoning to identify position. "What is Enhanced Positioning Technology (EPT)". Retrieved 2007-12-22.  Medic48 (talk) 23:10, 22 December 2007 (UTC)

The article talks about GPS systems that have speed, direction and acceleration sensors, that allow for very accurate, unambiguous dead reckoning. Most portable GPS, not having any of these external inputs can only use dead reckoning in a very limited way, i.e. when speed and direction remain constant, and the vehicle continues to travel on the same road. However it appears you are correct in stating that the TT920 has motion sensors that now bring some of these features to handheld devices too (presumably it needs to be mounted to the vehicle rather than being held in your hand to work though?). Anyway, the article needs an update to clarify this development... Socrates2008 (Talk) 23:26, 3 January 2008 (UTC)

BMW uses VxWorks and *NOT* Windows[edit]

All current BMW iDrive systems use VxWorks on a 32-bit Hitachi SH processor. It even states so on the iDrive page.

The very first iDrive system in a 7-series did indeed use WindowsCE. It might have also been briefly used in a 5-series, but it was never used in the 3-series and all current BMWs use VxWorks for iDrive. —Preceding unsigned comment added by (talk) 22:38, 3 January 2008 (UTC)

Primacy Dispute[edit]

I've added a lot to the section discussing who was first with automotive navigation systems. I think "commercially available" is an appropriate way to qualify the debate, since there were automotive navigation efforts conducted for basic research purposes somewhat earlier, and that doesn't seem to be an area of dispute. My NPOV might be suspect, since I was a consultant at Etak in 1989. I've done some work on both the Electro Gyrocator article and the article on Etak. —Preceding unsigned comment added by Yakushima (talkcontribs) 09:56, 18 April 2008 (UTC)

TMC (Traffic Management Channel)[edit]

Some newer models claim to be capable of altering their suggested route based on levels of traffic congestion and/or road closures. An explanation of how (and how well) this works would be interesting. (talk) 19:51, 20 June 2008 (UTC)

Purging original research inserted by Intersofia[edit]

Intersofia inserted unsourced original research at this edit on 18 December 2007 in violation of several core Wikipedia official policies (no original research and Wikipedia is not a soapbox). As Intersofia has failed to provide a source in over eight months, I am purging it immediately. The assertion is also factually incorrect as assumption of risk is not necessarily a complete defense to strict products liability in many jurisdictions. Rather, it is one factor to be considered by the jury under the comparative negligence regime.

For example, in a single vehicle accident, a jury might find the victim 20 or 30% liable for his injuries because he was playing with the GPS navigation system and driving at the same time, but might still assign 70 or 80% liability to the car manufacturer (of which some portion would represent the imposition of liability for not including proper safety precautions to protect incompetent drivers from themselves). Yes, this is crazy, but it's better than the old contributory fault regime where the slightest negligence on the part of the victim, no matter how tangentially related to the accident, prevented the victim from recovering anything at all. For example, under contributory fault, a victim who did not wear his seat belt and was thrown through the windshield would not be able to recover, even if there was clear evidence that the defendant ran a red light. --Coolcaesar (talk) 08:10, 5 August 2008 (UTC)


The photos used for illustration in this article all show legacy systems - does anyone have a photo of a modern automotive GPS? Socrates2008 (Talk) 07:57, 12 August 2008 (UTC)


I suggest moving this article to "stand-alone navigation device", as the article definitively focuses hereon. Also, it allows the article to be expanded with other (non-map) GPS-systems as the Garmin eTrex, ...

Speed limits[edit]

Many GPS/satnav units now contain data on speed camera locations but surely a better arrangment would be to have speed limit data for all mapped roads included with the option of warning the driver when the speed limit is exceeded ? Is there any reason why thisd isint done ? (talk) 20:21, 21 April 2009 (UTC)

Re: I'm not sure about other units, but my Nextar ME has this capability...the database has speed limit info which, if exceeded, results in a big flashing red circle around my speed. However, mine lacks the speed camera DB, so I suppose it's a tradeoff for avoidance vs prevention. —Preceding unsigned comment added by (talk) 14:23, 28 December 2009 (UTC)

Mitsubishi Electric as the first one to produce GPS sat-nav[edit]

The information about Mitsubishi Electric might be not true. The link given as reference doesn't work. The current address of ME history of 1990s is and it doesn't mention the GPS at all, neither the 1980s one. Kamczak (talk) 02:23, 18 January 2012 (UTC)kamczak


I've added a misdirection incident from Australia to the section in an attempt to make clear that this type of incident occurs worldwide not simply as was implied by the earlier version in the UK. A good single example from the United States would also be useful. Graham1973 (talk) 00:59, 18 March 2012 (UTC)

Werner Liebig[edit]

Just figured out I'd include Werner Liebig and his failed software company in the timeline, an article taken from here (and other German sources): — Preceding unsigned comment added by 2A02:8388:502:3D80:71E4:75DE:11A9:E465 (talk) 04:31, 25 November 2016 (UTC)
