# RV-14/14A – Known issues

### I cannot turn off the transponder in the GNS530 cockpit version

Because the aircraft comes with a G3X cockpit, the transponder is built-in to the G3X and cannot be turned off. This is a limitation of MSFS that we haven't been able to work around yet.

### GTN add-on is not showing in the cockpit.

To have any of the two GTNs available on the RV-14, you'll need Panel Mods, which are available [here](https://simworksstudios.b-cdn.net/Marketing_material/20241223_SWS_RV14_Panelmods.zip).

To install, open the folder of the mod you wish to install (i.e. TDS) and copy its contents into the MSFS Community folder. To revert to the default installation of the RV-14, remove the folders starting with "z-sws-aircraft-vansrv14".

Available mods:

TDS GTN: will make the RV-14 compatible with the TDS GTNXi, if installed.
PMS GTN: will make the RV-14 compatible with the PMS GTN, if installed.

### RV-14 tablet won't turn on.

The tablet on the RV-14 is empty on purpose.
