Various questions about Clio 4

Hello dear Clio friends after I was very happy with my Clio 3, it is time for me to get something new. I was thinking about a Renault Clio TCe 120 Limited de Luxe EDC. I have looked at the price list and the features and have a few questions about it … Can the MediaNav Evolution be replaced with the above-mentioned equipment? Lt price list obviously not possible. I’m mainly concerned about the TomTom cards, which I bish It seems that NavTeq cards are pre-installed at MediaNav and I don’t know if I like them. So I’d rather be on no. The other question concerns the seat heating (driver’s seat). Unfortunately, this is not included in the package at a Limited de Luxe EDC and is obviously not offered. Is there a seat heating suitable for Renault Clio, which you can recommend to me? I think of something where the installation is not very expensive / expensive. Hoff e, I can help myself and would like to thank you very much for your suggestions in advance
