Thanks for responding to this issue HTC.
JB73, here's my workaround till HTC implements the icon change.
I have created different engine sounds for the 109 G10 and FW 190 D9. That way I can tell instantly from the engine sound if it's one of the other 190s or a D-9, same for the 109 series. The differences between a G2 or G6 are not that big, but a G10 is a big difference.
Just go into your sounds folder, make a copy of the original G-10 sound and save it as G-10bak. Remember the correct file name, then delete the G10 sound file. Then choose any sound you want for the G-10 engine, for example the 262 jet engine sound. Make a copy of the 262 engine sound, then rename it to the G-10 file name. Voila, when a G-10 is nearby, you know it because it sounds like a jet engine.
You can get pretty silly with this. You could make sounds like a voice saying " A8, A8 , A8 " or assign the tank tread sound to the A8.
