tylko dla modelu lan1050 https://obrazki.elektroda.pl/3654104700_1589218722_bigthumb.jpg https://obrazki.elektroda.pl/2926498300_1589218811_bigthumb.jpg Dziwne powinno działać :/ Podepnij jak powinno być. Obstawiam ale mogę się mylić że poza wymianą nawigacji będziesz musiał (o ile już nie masz) wymienić sterowanie z kierownicy jeśli masz takowe sterowanie to wciśnij ten przycisk i przetestuj. Ale źle to odczytałem to opcja voice recognition mode hyundai czyli komendy głosowe. Skończyły mi się pomysły. Może na odwrót podpinasz mikrofon tam na schemacie jest o ile się nie mylę dioda zenera jak źle podepniesz to obstawiam ze nie zadziała. https://obrazki.elektroda.pl/1914236300_1589218513_bigthumb.jpg Źródło

GENERAL PART (NAVIGATION)
Cannot identify current location. (GPS not receiving)
GPS cannot be used indoors and must be connected to a power source with ACC in a vehicle in a location
where the signal from the satellite can be received easily.
When initially connecting the GPS, it usually takes about 10 minutes to be working normally, but the connection
speed can differ depending on the weather condition and surrounding obstacles.
If the GPS connection is unstable for a long period of time, try the following.
• Check if the product is connected to a power source.
• Check if your vehicle is in a location where the sky can be seen well.
• If there are high buildings or if you are under a tree, move to a location where there are no obstacles.
Cannot hear the voice guide.

Map matching
As mentioned, the GPS systems used by this Navigation System are susceptible to certain errors.
Their calculations may on occasion place you to a location on the map where no road exists. In this situation,
the processing system understands that vehicles travel only on roads, and is able to correct your position by
adjusting it to a nearby road. This is called map matching.
With map matching.
With no map matching.
