Freelander 2 (LR2) Radio Upgrade

Hi! I'm looking for new android car stereo and want to install Seicane car stereo in my Land Rover Freelander 2. How to install it? Is it difficult to install this by myself or to ask the professional to help?

If it's anything like the android unit I installed once it will come with all the necessary adaptors so should be a fit and plug in solution
Looking at the link can't help wondering if is made by incredibly small people ...

I don't believe it's that easy to swap out the stereo, especially on models that have reversing sensors and or power amplifiers fitted.
I'm sure the sound from the reversing ECU comes out of the stereo speakers. I also believe the dash clock gets it's time from the factory stereo system. So that could stop working, with a different stereo fitted.
