fusionman

First of all thank you for having me, now down to business I have a 2007 ford fusion and need Bluetooth and would like dab as well .I have seen the fusion titanium has an oval (not the square one) sony radio in but not the dab one that I think you get in the newer focus among others ,so the question is can I fit a dab sony radio in to the surround that fits in to the fusion/mk6 fiesta ? I hope that makes sense , I have read a thread on here were some one did it but I am not sure how he got the surround to fit
Thanks for your help
