Almost any double DIN radio unit will fit. Good news for you there are some outstanding alternatives to the Axxera. I replaced my Axxera with a Kenwood.

Kenwood has several models to choose. It was a drop in. Function and performance that blows the Axxera away. I particularly like the dual Nav and rear camera display.
