I've compared the products on Garmins website & they're exactly the same, except that;

City select is for;
GPS V, 196, NavTalkGSM phone, iQue, 60C, 60CS, 276C

City Navigator is for;
Streetpilot III, 2610 & 2650

Anyone know why they're named differently and only available for certain models, but doing the same thing?

Is it something to do with the GPS units themselves?

Just curious really

CN vs CS

There should be a post here from PanEuropean about the differences. Yes, the mapset (cartography) is the same, but CN has additional attributes that provide more detailed directions. Not all GPS devices can utilize these additional attributes.

See if this thread answers your question.

When I get a route from MiGSel from his 2610 he uses City Navigator - when I save it into my City select and recalculate it so that I can upload it to my 60c invariably the route total distance will change very slightly. When riding the route there is practically bugger all difference - perhaps one or two small deviations along a route from Dover to Andover for example - not worth worrying about.
 
Both products (CN and CS) are made by the same company - Navteq - and both contain exactly the same visible street and road information. Each one will run on any of the GPSR's you mentioned in the post at the top of this thread, in other words, you can use either one in any autorouting GPSR.

CN has a few more invisible attributes associated with each street or road. These invisible attributes probably account for the slight difference in routing and distance you noticed. The attributes allow the higher-end automotive GPSR's to provide slightly more precise route guidance. For most of us, who are moto riders, we would not notice the difference between using one or the other in the same GPSR.

Garmin recommends using CN with the SP III and SP 26xx (it is supplied with those units) and CS with other GPSR's that are capable of supporting autorouting. Very little is gained if a person purchase CN to use in a GPSR for which CS is recommended, however, the price of CN on a standalone basis (without a GPSR) is about double the price of CS.

The really detailed answer is a lot longer than this, but what Bill wrote is 80% of it, and what I just added brings it up to 90%.

Good point. What is probably happening is this: CN has more invisible road attributes that identify the suitability of any given road for different types of vehicles. So, when MiGSel calculates a route with CN, it knows he has a motorcycle/car, and picks streets accordingly - perhaps making use of the odd shortcut that would not be available to a larger vehicle. CS doesn't have quite the same granularity, which means that the odd tiny optomization - such as, perhaps, using a left hand turn at an intersection, rather than a ramp at the same intersection - is missing.

The difference between the routes will be squat-all in real terms, though, as long as you are using the same version of both. The differences on a 100 mile route could be measured in 100's of feet, and if you rode the route twice using CN on one trip and CS on the other, you probably would not even notice the difference, unless you were observing your previous route tire track through a snowfall.

On a slightly related subject, I have seen mention that CS v7 is probably the end of the line with City Navigator NT v8 taking over on the Quest 2

If this were to be the case do you think it possible for Quest owners to purchase and successfully run the newer mapping pruduct on their GPSRs?

This is a tough question to answer, because I have to skirt carefully around non-disclosure agreements that limit what I can say in public. I will try to give the best answer I can, you might have to read between the lines a bit to figure things out. I'll give you information in point form, that is probably the easiest way.

1. Keep in mind that Garmin themselves don't really want to have two similar but different map products out there (CN and CS). If it were up to Garmin, there would be only one map product, and it would work in everything.

2. From point 1 above you can probably conclude that the reason that two different (but apparently very similar to the end user) map products exist must have something to do with the contractual and licencing arrangements between Garmin and the owners of the copyright to the cartography. As I have mentioned many times before, Garmin is a hardware company, not a map company. They don't make a single map themselves, never have, never will. They buy cartography from other companies and simply package it in a format that Garmin GPSRs can read.

3. The 'NT' version of cartography that has recently come out is called 'NT' because it supports traffic information broadcasts (which, oddly enough, don't use lat/long to describe locations, but use a proprietary grid). NT cartography supports this TMC grid, nothing more. So this whole NT thing doesn't signify anything at all other than TMC support.

4. In past years, the cost of the memory that was used to store cartography inside the GPSR was fairly high - we all remember paying $100 or more for a 128 meg chip that fit in a SP III. Heck, I can remember paying $100 for a 32 meg memory chip for a SP III ! Today, that kind of memory is so inexpensive that Garmin is installing 2 gigs of solid-state memory in most new GPSRs - that is capable of holding an entire continent of maps. This means there is no longer a need to supply CitySelect simply because map segment sizes on CS are a bit smaller than map segment sizes on CN.

5. For the end user who drives an automobile or a motorcycle, the only apparent difference between CS and CN is the text depiction of what is written on overhead motorway signs. For heavy duty industrial use (e.g. delivery companies, large trucks, fleet management) there may be other differences that might be significant to those kind of users. However, advances in technology might make it possible to cater to these two different user groups (individuals vs. businesses) with the same packaged cartography product.

6. I strongly suspect that if there is no longer a reason (provided by the cartography providers) to ask Garmin to publish two different cartographic products (CN and CS), and memory capacity is no longer a concern, Garmin will do the obvious and consolodate some map products in the future. OR... they might start distributing map products that are specific to a certain model of GPSR, if all the user needs to do is update the whole darn GPSR once every 12 to 18 months. Either of those actions would simplify things for both Garmin (from a logistics point of view) and for the end users (less confusion).

Personally, I have heard nothing at all about CS being discontinued. But, as explained above, the technical justifications for having the two different products seem to be fading away, so, as soon as the licencing issues can be sorted out to the satisfaction of the map producers, I personally can't see any reason at all to continue on with both a CS and CN product.

Again, this is all my own personal opinion and forecast - don't take it as a statement of fact or an insinuation of what Garmin plans to do.
