I just bought my first car which ended up being an 05 Celica GT with 53k miles. So far I love it except for a few "annoyances"
1. When I lock and unlock the doors, there is no "beep" or "chirp" sound. I have to look for the lights. Is there any way this can be enabled again? Can anybody with a similar vehicle confirm that the Celica does in fact have a lock/unlock sound.
2. I am wondering if I have a factory installed anti-theft device. How do I tell? I have a panic button on my OEM remote and that does work when I hit it.
3. Could anybody please tell me what type of tires they have on their car or what are good tires to buy. My current tires are 5 years old at 60% but are extremely loud. I am planning on replacing them just because of their noise.
4. I wanted to add the OEM auto dimming mirrors which include the compass and temperature display. I do have a factory installed cruise control so is it as simple as plugging in a wire? Anybody want to trade for a regular mirror and some cash for one?
5. Performance wise, this car isn't that great. Acceleration is mediocre at best. Any quick suggestions to improve that? Something the average user can do. I know the internals of a car well but I can't work with engines for my life.
6. I wanted to connect an iPod dock to my factory sound system. My friend has a dock that basically shows what the ipod is playing with a second hit of the CD button. His dock though is so faded that we can't tell which one it is. Anybody know which one he might have or another one that'll do the same? I refuse to use the FM transmitters because of their terrible quality.

Any answers would help me out a lot. Thank you in advanced.
