has anybody tried installing a hud on their car. I have a 2003 without the hud and was wondering if it could be done.

I believe you would need a new dash and and all the hud stuff. I hate taking apart dashboards.....

i hate it to but my friends like it. I know i can get the hud unit but i need a new dash piece..but what im really wondering is if the car has the wiring for it.. like my old nissan had all the wiring for the heated mirrors and heated seats so all i needed was the new mirrors and the new seats.

It isn't all that difficult if you have some degree of technical and wiring experience. All signals required for the HUD are accessible at one point or another within the dash. Basically, you need:

Vehicle Speed Signal
Left Signal Lamp Supply Voltage
Right Signal Lamp Supply Voltage
High Beam Indicator Supply Voltage
Class 2 Serial Data Bus
Power
Ground

You will also need to wire in the control which is located where your cubby hole is left of the steering column. Again, this isn't difficult since all these connections can be made at the HUD unit itself.

Just about all the signals in the above list can be obtained from the instrument cluster connectors.

does the windshield need to be changed for it to work?

No it does not NEED to be changed, but the display will be a bit blurry. A hud windshield makes it much clearer

jshelton added a HUD in his 2000 SLE

well im going to attempt to install the hud as soon as i get all the parts.

Exactly. However, if at some point you need to replace your windshield you may want to have the HUD version installed then. It is more expensive though.

If you hate it Id say put money and time into other areas. I say this because, im not sure how it is in the bonne to take one out, but in a ford taurus taking the dash out was quite a chore, let a alone putting in something that wasnt there from the factory. Just ask yourself if you really want it. I rarely look at my hud, unless the po po are around. dropping a dash can be a pretty large task if you dont have that much mechanical ability. Not trying to stop you from putting one in, but trying to save you some frustration
