I am not sure if my GPS is faulty, just been to the car, you have 2 options under GPS simularor
1/ on
2/ off
when I put on, I have no blue bar on the screen under acquiring satellite
If I put off, I have the blue bar moving for position
also I passed near a new road in my area, this road is not on my sat nav but I am sure it was last week before to disconnect the areal
I am pretty sure I pay for updates my map 2 or 3 years ago
I am just thinking maybe something we did was wrong and I lost my map and now I am back to my old map and the car lost sat nav when I drive on road not on my map
I put few pics for you can look
best regards
That screen is for the simulation mode or route planning.
The OFF setting is for using the sat nav and connects to the gps satelites. Which is the normal mode.
The ON setting is for planning a route without gps connection so you can plan your route.
If its in the off position and your seeing the blue bars moving then your GPS antenna is trying to work and get a lock on the satelites. If i remember correctly it needs to get a lock / high signal on either 5 or 7 satelites minimum but can recieve upto 12. If its not getting a lock on the minimum number of satelites then the home screen signal bars will remain grey and hollow. Once the minimum number of satelites is achieved it will turn green and show between 1 and 5 bars as the number of connected satelites increases.
The aerial on the roof is connected via a long extention cable to the back of the NIT which is behind and below the info screen. From what i can see its a fakra connector for the GPS.
If your sure it was working before your italian stripe was put on then it really could be as simple as taking it back to whoever put the stripe on and get them to check the aerial connection its either not connected properly or its been damaged while they removed it.
Hopefully its just the connector has unseated.
If that doesnt solve the problem. Then its either a replacement roof aerial at £70 plus or a cheap univeral one.
If you go down the cheap universal route then you need to be comfortable taking the infotainment bezzle and screen off so that you can access the NIT. You can dash mount the new GPS antenna and route the cable to the back of the NIT.
Have a look at the screen shots above. The first picture is the back of the NIT you can see the blue GPS connector on the left side at the bottom.
2nd picture is the connector plug on the gps antenna in picture 3.
The maps not being upto date is a seperate issue. If you cant get the system to pick up the satelite signals the latest maps will do nothing as the sat nav wont be able to use them except for route planning (simulation) mode.
