I have to assume you have the same car me -

My car is TR spec with no NAV as in the following picture - 

You have the Nav version with reverse camera which is in TR (Nav), T4 and T-Spirit models. I think that it it is TNS510 or similar. You want to install an aftermarket stereo?

Read the following to understand the problems. There are suitable adapter cables made by Connects2 or Autoleads to connect aftermarket stereos including steering controls. The tricky items are the reverse camera, the auto volume and connecting the internal mic.
