I used the CIPA from Amazon with compass and outside temp. The dimming feature is first rate--really fast. Temp and compass are accurate. Can read in F or C--just press a button. Ran temp wire at "A" pillar in back of air bag using a "fish"--no need to remove "A" pillar molding and nothing to break. Ran temp wire through firewall at rubber grommet 9" or so above steering linkage (near gas pedal,) from engine compartment in using "fish". Attached temp sensor in plastic panel, slightly depressed, under bumper, in line with fog lamp on driver side. Gets some protection from ice and snow. Used "fish" to get wire there. Cut small slit in plastic with Dremmel tool to attach temp sensor. Looks like it could have come from factory that way. Has crimp on connector for power that accepts included detachable spade lug. Came w/plastic flex conduit over entire length in engine compartment--nice. I'll do pics if someone is interested.

 

Thank you for your details on installation. It sounds similar to what I did.
