RESTORING INFO AND SELECT BUTTONS
To restore the info and select buttons after loading new software (from BMW information):

Recognition of country-specific functions:
To enable the country-specific functions of the softkeys to be correctly activated by the
navigation software (valid from operating software version V16), the following routine should
also be performed:
1. After loading the operating software and encoding the navigation computer, the radio
must be switched on once. Only then can the graphics component of the navigation system
record the status of the radio.
2. After disconnecting and reconnecting the battery in vehicles with the current on-board
monitor radio versions and the new on-board monitor, the radio must likewise be switched
on once to enable the navigation system software to recognise the operating status of the
radio and to activate the appropriate softkeys.

====================================================
I'll bet that your INFO button does not work either. This is common after a 16:9 screen upgrade. When you first install and code a nav unit in you need to do a radio on-off-on sequence to "introduce" the radio module to the nav computer and the 16:9 screen. The BMW TSB below gives you the background of what you need to do.

The challenge for us DIY folks is that we can not code our navs, so
after doing an upgrade to the radio or any other nav part, we can not
initiate the state that makes the display and the nav computer
receptive to the radio introduction. However, a few folks discovered that the nav enters this state when you downgrade to the V23 CD and then do an upgrade. Other CD versions may also work as the downgrade target, but V23 seems to be the one that has worked best for others.

The 2nd post below describes the sequence that you need to do to get the INFO and SELECT buttons activated. So you know, this will kick you into Euro mode, which eliminates the Accept screen and displays your shorter distances in yards instead of feet.

I have seen a few posts from folks who have had persistent lines in their displays. This may be a defect in the screen.

Lite onödigt vetande om Navigatorn.
Vad står siffrorna 2-1/81 för?

Första siffran står för vilken Navigations Generation du har.
1=MK1
2=MK2
3=MK3
4=MK4

Andra siffran står för Navigations Variant

1=Färg skärm
2=Monokrom skärm/ Radio navigation

De sista står för revisonen på mjukvaran i Grafikenheten.

21= SW 2.1
80= SW 8.1
osv.

Jobbet att uppgradera är tämligen lätt.
Har du en CD med senaste mjukvara tar det ca 5min.
1. Tändningen måste vara på läge 1 (terminal R) hela tiden.
2. Stäng av alla elförbrukare som du kan, lyse, radio, fläkt etc.
3. Välj GPS Navigation i menyn på TV navigatorn/ radionavigatorn.
4.Ta ur Kart CD:n ur CD-läsaren. Lägg i SW CD:n istället.
5. Följ instruktionerna som kommer upp på navigatorskärmen.
6. Efter att medelandet "Software has been successfully loaded" ta ur SW CD ur CD-läsaren.
7. Konfimera laddningen med att trycka OK på navigatorn.
8. Sätt tillbaka kart-CD:n i läsaren.
9. Klart att använda.

Ett litet tips till.
I menyn välj Set eller om den heter Setup (den där man ställer klockan osv.)
Håll in MENY knappen i minst 8 sekunder.
Vips är du inne i en Service Mode till navigatorn.
Där inne hittar du en massa skoj.
Tex. GPS-tid, antal mottagande GPS satelliter med signalstyrkor, Latitud, Longitud, Höjd över havet, kompassriktning i grader (0 =norr), Hastighet i m/s (gångra med 3,6 så får du km/h) uppmätt med GPS med två decimaler och en massa till som jag inte kommer ihåg på rak arm.
