Nice work! I've got a 9th Gen Corolla that I'll put up here soon. I did things a little differently though, it'll be fun to compare.
The USB GPS receiver I originally had wasn't quite living up to expectations (satellite acquisition took an eternity). I replaced that one with a Columbus V-800 (5Hz update is what sold me) - actually worse than my other one was After tinkering with the firmware on it and reflashing this, and changing that - let's just say it's decoration at the moment... I broke down and decided to buy the new GlobalSat BU-353-S4 with the SiRF Star IV chipset (got it from MP3Car's Amazon store). I read some good things about that chipset, hopefully it works well with iGuidance 2011. I'll comment on that when it arrives - as long as it takes less than 5min to find 1 satellite I'll be happy

I am placing it inside my car on top of the dash... I know it's not the optimal location but I've had a few GPS receivers in the past that worked just fine inside the car. Also, I don't believe that these other GPS units were waterproof. I will try this new one out any hopefully it works well - if not, I know that this one is waterproof and I'll find a good spot on the outside of the car if I have to.
what on/off configuration did you use on your M4-ATX?
This is great, I was looking for a cheap alternative to boost the Volume.
The Clarion seems the way to go.
