NAV connect issues

Hello again. I cannot seem to get my NAV to work. I read through all the threads I could find about fixing this and am having no luck.

Everything seems to be in working condition but the screen just shows the arrow and no map. It just looks like I am in the middle of the ocean. It shows some random lat longs but that is about it.

The previous owner said everything was working fine for him until he took the antenna off the top of the car and ran it through the car wash. when he put the antenna back on the car everything was working but the NAV would no longer provide directions or give a map picture.

I have done the manual resets both when the engine is on and off. The screen just goes black and comes back on again. I have looked through the hidden service menu and everything is in green, except the sim card because I do not have one.

Any other suggestions?

Re: NAV connect issues

Hi, Welcome to the FF.

You need a valid map disc in the unit for it to work. As there were no map discs published for the USA, it will never work for you.

Re: NAV connect issues

I live in Germany and have all the Europe maps. Like I said the previous owner said the system worked two weeks ago before he took it through the car wash.

I am wondering if him taking the antenna off may have done something to the connection.

Re: NAV connect issues

The aerial is designed to be removable. The previous owner may have damaged the mounting base whils removing/refitting the aerial. Check for marks on the roof around the mounting.

Is it a Connect Nav, or a Connect Nav+? The former is only designed to show arrow direction symbols, not pictorial mapping.

If it's a Connect Nav+, it can be changed to show either arrows or pictorial mapping via the "SETUP" menu.

Re: NAV connect issues

I am pretty sure it is just the connect Nav, not the +.

Re: NAV connect issues

If it's the basic Connect Nav, it doesn't show pictorial maps. Strange that the previous owner said it did though.

Was your unit original factory fitted? or was it retro fitted by a previous owner?

Post a picture to include the screen showing the direction arrow.

I've heard that there's also a very basic Connect version too, but I've never seen one of those in the UK.

Below are pictures of a Connect Nav that only shows arrows, and the CN+ with multi colour pictorial mapping.

Re: NAV connect issues

OK I definitely have the connect+ with the color mapping.

It is factory fitted.

I will post a pic later tonight when I have a chance. Thanks for you help so far!

Re: NAV connect issues

Only time I've seen the red arrow on a blank background is if I have the wrong disc in the CN+, i.e. if I have a France disc in while I'm (the car) in the UK.

Assume you know that the map for Germany is divided over 2 discs, Germany North and Germany South. Could you have the wrong one for your location in the CN+?

Re: NAV connect issues

Yes I have both disks and it doesn't matter which disk I have installed.

Re: NAV connect issues

You've not said anything about getting a "CD ERROR" when inserting a map disc so I would assume the map data on your discs is OK.

Only other thing I can guess at, is that the SatNav module within the CN+ isn't interpreting the data correctly to display the map. Unfortunately the modules are not available seperately. There's a company in Germany that repairs CN+ units here: http://www.pavlek.de/fiat/index.htm

Alternatively, it may be less expensive to get a replacement unit from eBay. They sell for between 100 and 200 (GBP) in the UK.

Re: NAV connect issues

I just think it is weird that i worked a few weeks ago and stopped when he messed with the antenna on the top of the car. I will try and mess with the antenna and see if I can get it working again.
Thanks again

Re: NAV connect issues

Does seen a strange coincidence. The aerial rod just screws onto it's mounting base by hand. The mounting base is fixed to the roof by a single nut inside the roof. Only way I can see that the previous owner could have damaged it, is if he turned the aerial so much that it also turned the mounting base and broke one of the wires below it. That's why I suggested in post #4 above, that you look for marks on the roof . Also, if the wiring had been damaged, your diagnostic wouldn't be showing "GPS Antenna OK" as in your post #8 above.

Re: NAV connect issues

Just checked mine with the GPS aerial (grey plug) disconnected from the CN+. It still shows accurate Longitude/Latitude coordinates and current location mapping whilst stationary.

While driving the car with the GPS aerial disconected, it still updates the coordinates and map location, from data received via the CAN network, from the wheel speed sensors and steering angle sensors, but the displayed information is not so accurate.

My money's still on your SatNav module.
