Turbo gauges retrofit in a GTS - a few questions

[el greggo]

Hello all

 

Planning to replace the gauge cluster in a 2010 GTS with a Turbo gauge cluster and have a few questions.  In researching this swap, I found some references in the archives to swaps done as far back as 2006 or so, but no answers to the questions below.  I did a test fitment this past weekend and planning to do a permanent swap in the coming weeks when mileage on both clusters is the same (or within 10 miles or so!)

 

1. In the settings on the Turbo cluster, COMFORT is in all caps and subsequent menus overlap in all caps.  It appears setting can be set.  Does this quirk affect usage at all?
2. Is it possible/simple to swap the clock set button + trip mileage reset button?  On the Turbo cluster the clock is half worn off, but on my GTS cluster it is perfect.  I would like to keep the better looking clock set button if possible/simple.
3. Any possibility of swapping in voltmeter on Turbo cluster?  I know the gauge front is one big piece and may be tough to get right, but more wondering if the electronics are there and would be plug-and-play behind since the wiring sends the battery/electrical volt data to the cluster. (clearly I am not an electrical engineer!)
4. If question 3 is an absolute NO, then how do you Turbo owners know how many volts your battery/electrical system is putting out (without the use of a radar detector that can tell you)?

 

Thanks for reading this far, and thanks in advance for any useful responses to my queries above.
