This is entirely your choice whether you want to keep your warranty or not as if you get the Android panel and front camera installed from any good shop other than the Toyota's dealership, then most probably, it will VOID your warranty, but the problem with these dealerships is that they will charge you much more than what you can get outside.
If I were at your place and I want to get the Android panel and front camera installed, I'll get it from outside as normally these warranties from the dealerships really don't matter that much, unless you want to claim it whatsoever.
Hollywood Beats in Chah Sultan, Rawalpindi is the best place to go for such work.
The rest is your choice.
I hope it helps.
