Review on Metra 99-7523S: Silver Double and ISO DIN Radio Install Kit for 2003-2005 Mazda 6 by Genene Locson

I ordered this dash kit for my 2003 Mazda 6i to install a 2 din stereo with navigation. Unfortunately I tried a few stereos and had to send them back as the hole wasn't big enough. The actual opening for this dash is 6.85" x 3.95". All the stereos I've tried are 7 inches in the front so they won't fit unless you change the hole. I got the hole size from @Metra tech and also measured it myself, looks very good in the cabin but the opening issue is a big problem.
