I have a bunch of updates I didn't put on here to bring this thread up to date, starting with..
If you read all of this build thread you might have seen earlier my earlier comment about installing a full FIS (and replacing the faded centre LCD). I've seen a few comments on this forum and on other forums before where people just don't "get" the purpose of the Golf MK4 / Bora full FIS instrument clusters compared to standard clusters. I remember seeing comments on another forum advising other people not to buy them because they are "not worth it", even interrupting sales threads to say to others "don't bother". Harsh! Depends on what you are into I guess, if it's just a "show" style car that doesn't get driven that much then fair enough.
I know plenty of people on here have seen full FIS clusters before, but there are always people relatively new to the MK4 Golf / Bora, so here is a bit of a run down on what a full FIS can offer you that half FIS can't.
So a standard Golf MK4 cluster looks like this -
As the MK4 platform is dating back to the late 1990s the standard type half height cluster LCD centre screen looks pretty basic compared to the displays in modern cars, a full FIS cluster can help to bring it up to date.
Full FIS photos - these a mixture of photos from my previous 1.8T GTi and my R32 / Bora (though the Bora cluster is now also an R32, some of these photos are from when it was still a "sport" cluster).
The basics - FIS menu
Basics - open door display (depending on if your CCM supports it and if you have enough doors
)
General warnings (some of which you don't want to see usually, there are more including oil level / pressure amongst others, luckily I've not seen one of those for a long time..)
Fuel
Washer fluid
Brake pads
Coolant / cooling system
If an OEM radio is connected then the FIS LCD can display the radio station or CD / track number being played.
(temporary cluster I built for my previous 1.8T, R32 style, but has standard 160 mph top speed)
OEM VW MFD satellite navigation, which displays some of the route information on the FIS (and CD / Track number), as below:
(Bora sport 160 mph)

OEM VW satellite navigation can display bars that indicate at which moment to turn, along with spoken directions given by the headunit
The MFD was really handy as I had the TMC unit connected to it, it was combined with a TMC enabled navigation CD so the MFD could receive traffic updates and adjust the route automatically to avoid traffic delays
(Bora sport 160 mph in my old Golf)
Phone kit
If your OEM head unit has some type of phone kit enabled with the "mute" line wired in, when the phone kit is active the radio will be muted and the display will indicate "PHONE".
Advanced Bluetooth phone kit
If you have an OEM head unit that has a more advanced Bluetooth kit installed that can read the phone contact list, it may be displayed on the FIS
Advanced OEM head unit
If you've gone to the trouble of retro fitting a more advanced OEM head unit from another VAG platform / generation then you may be able to view extra information on the FIS display:
MP3 track titles from an SD card
Compass (with MP3 song title above it). The Compass is not that useful usually, but available if needed.
(Bora sport 180 mph)
MP3 track and navigation - again if the head unit supports it (has to be an OEM not an after market) the MP3 track name can be displayed along with route guidance
So I think what it comes down to is that for those people that moan about / don't understand the full FIS display, they probably never connected anything external to it, I guess it would be similar to someone buying a new fancy LED TV but not connecting anything to it and then moaning about it
. It probably also depends how much you drive and if having extra information displayed is useful or not. My car is a daily and gets driven all over the place so it's pretty useful for me. Hope that helps anyone wondering if a FIS cluster is worth having or not
If not, I have a couple more FIS display related updates to come...
