[attachmentid=17805] :nono: Mike, I just tried it and I don't think you could make it work. I have a 2004 Mazda6. Last year I went with the Metra kit and installed the Pioneer AVIC-D1. That's the double DIN radio with NAV. I purchased a Garmin Nuvi 660 two weeks ago. I do high recommend the Nuvi 660. It's my third Garmin along with two cars (plus the Mazda) with factory style NAV. The Nuvi 660 is the easiest GPS I've ever used and has the best features. The biggest plus is satellite reception, it doesn't have to be on the dash. I've used it in the house and can't believe it will pick up a signal. The downside is mounting. It comes with the suction mount. I ordered a vent mount off eBay, but it won't work with the Mazda6. To use it in the Mazda, I would suggest using one of the center AC vent. Pick one of the three, close it off, and attach the suction cup mounting disc with the attached two sided tape. This will provide the best physical location and ease of use. I didn't necessarily buy the Nuvi 660 for use in the Mazda. I have two other vehicles without GPS. The Mazda6 is my daily car and I LOVE IT. Several notes about the NUVI 660. It's currently one of the most expensive portables available. I got mine at Sam's club for $788. eBay averages about $725-$750. I like the physical appearance of the Nuvi 660. It big screen, 4.3", slim, and attractive. The Bluetooth function works well. Good luck with your decision.
