Thoughts & recommendations please - Change of headunit from Kenwood Dnx521dab for Cali T5.1

[FredFlintstone]

Hi,
We have a Cali T5.1 and would like to upgrade from a Kenwood dnx521dab.

We need front & rear cameras.
We'd like DVD, but not 100% essential.
Need to be able to integrate with steering controls etc.
Doesn't need Sat Nav as well use Android Auto with Waze etc.

If anyone has any good recommendations or perhaps something surplus?

Best regards
