Ford C-MAX Navigation

How is the A6?  What do you mean? 

It'll be exactly the same as the A4 except it will include any road, restaurant etc. changes since the A4 was published.

I've been reading this thread and thought I'd pipe up since my nav was acting goofy until recently.

 

A few weeks back I noticed that my nav position on the map would become more and more out of whack as I drove.  To illustrate, sorry I don't have a video, but my nav plot on the map would be accurate at my starting point, but 2 or 3 miles of driving and the map would show my position as being a few hundred feet, or possibly a half a block ahead of my actual position.  So, If I were sitting at an intersection the map would show my vehicle halway up the next block.  In this condition, if you makde a left or right turn, the GPS would have you between roads in the middle of the block.  Sometimes the GPS would correct itself and get the marker back on a road, sometimes I would not do any correction.

 

I called Ford's in-vehicle support line and they told me that I'd have to contact my dealer.  I took the vehicle into my dealer and according to the work order there was some kind of update or nav system update that they applied.

 

The work the dealer performed didn't have anything to do with the map data card, it was something they had to apply with their diagnostic computer in the shop.  I'm under warrenty, so no charge.  I have no clue what it would cost to do that work if I were not under warrenty.

 

My C-Max came with the A5 map card.  I recently acquired an A6.  Because I had two map data cards, I was able to test the map location accuracy with both map data sets and I had the same incorrect plotting on both cards, so the issue isn't with the map card, but with what the onboard navigation computer is doing to plot your place on the map.

I currently have the A4, how is the A6??

The A6 should be an improvement.  I have an example from the region I live in.  There is a double round about on an exit on I-90 westbound on the far east side of Bellevue, WA.  This particular traffic control item has been in place at least 18 months if not 2 years or possibly longer.  I don't live in Bellevue, but I visit it a few times a year.  The A5 chip didn't have the roundabout structure in its map database.  The A6 chip does.

 

So, I'd say that if there have been road changes or improvements in the past 18 months in your area and they are not reflected on the A4 that you are currently using, then you'd probably see some, if not all of those changes reflected on the A6 chip.

 

Incidently, I purchased my A6 chip off from eBay for half of what Ford's official side was offering it for.  The A6 chip came shrink wrapped and packaged in the same material as my original A5 chip that came with the car, so I know it was legitimate.  I have a Garmin Nuvi and I still believe that the portable navigation makers do a better job and keep their maps updated to a higher level than the auto makers.  What I do like about in-dash nav is that it is in-dash and you don't have to have a device on top of your dashboard or stuck to your windshield.

I'm having a similar problem with my Energi. They reset the nav the first time, but it has happened again. I'll have to take it back in. For me it tends to be off to the right of the car about 200 yards to a half mile. But only sometimes.

I have an A4 map card for my CMax hybrid and it just quit working. It says on the panel "install new SD card" Should they quit working like this?

Try resetting the card.  It's in your central console next to the USB ports.  If you push on the card it will release.  Pull it out and reset it by pushing it back in.
