[tech2]

my gf was ran off the road by a truck today. luckily she is ok unfortunatly her passenger side mirror was destroyed by a mailbox. i need a cheap quick fix. her truck is a 2007 h3. i was interested in replacing her mirror with this one.

when i was taking hers apart i unplugged 2 wires from it. in the pictures of the one i would like to replace it with it only has 1 wire. thoughts on what functions/features we would be losing out on if i bought this one and installed it. thanks for the help
