If you want turn-by-turn you actually have two options.
1. Download Waze. It's in the Market and free. This app gives you spoken turn-by-turn. I haven't used it in a while but when I did it worked great.
2. Update your phone to 2.1. If rooting your phone is out side your comfort zone then be aware that the Release Candidate (Like the other guy said AKA OTA Leak v2) is final on your phone, there is NO WAY of going back to 1.5, your stuck. HOWEVER, the navigation works really well on this leak.
If you would like to try it here are the instructions. Be warned that you could "Brick" your phone. I haven't heard of anyone doing that yet but it is a risk.
· 2.1 Leak 2 - NEW
· 108,819,939 bytes (106,270 KB or 103.81 MB)
· Download: PB00IMG.zip
. Save this file to an easily remembered location on your computer. (i.e: My Documents)
IMPORTANT: DO NOT RENAME ZIP. IT WILL NOT WORK OTHERWISE.
· Turn OFF Eris
. Plug your phone into your computer via usb.
. Pull down the USB menu that appears on your phone and use as a disk drive (Mount Phone)
. Open the new disk drive that windows created (Removable Disk E:/)
. Drag the downloaded file from the location where you downloaded it to onto your SDCard. DO NOT UNZIP OR RENAME THIS FILE!!!!!!!!!!
. Follow the next steps.
This is the Point of No Return
Once you do this, you cannot go back to 1.5, PERIOD.
· Charge your phone at least 50% or more.
· Start Eris by holding Volume DOWN and Power / End Call Buttons.

If you run into trouble, I will try and help you. I followed these instructions step-by-step when I upgraded my phone and it work with out an issue. You will need to re-install all your apps. One way around this is to use an app called appBrain or appsaver. appBrain backs-up your apps to the internet, appsave saves the apk file to your SDCard.. Remember to back-up any and all important texts or other file you have on your phone.
