I went ahead and orderd this unit and it was pretty easy to install I put a write up on there website, I couldnt find any info on this for the M, only the G and maxima. Great unit, just hit lock twice and all the windows go up, it also has a programmable option to have the doors lock after the ignition is turned on. that is kind of sweet but they dont unlock when you turn the ignition off, that kinda sux.
Check it out.
