i put on the clifford avantguard 5.1 w/ remote start on my manual
trans. I would not recommend this to install to anyone other than a professional. It cost me $500 for everything and I spent about 3 days with the entire dash torn apart. Not 3 full days but close. I have accidentally started the car because my dad moved the car and left it in gear and barely any e brake on. Luckily i stopped it before it hit the large rocks in the front yard.
You get used to using your parking brake with out leaving it in gear unless on a steep hill. At any rate you don't always use the remote starter. It also has a turbo timer function sort of.
But i do not reccomend this system if you tend to be clumsy. And professional install only.
