I got a Hitachi MMP-501B with 5" screen

A little bit bulky.
It has its own antenna, a square one that you pull from the back of the unit. It picks up satellites very easy even indoor in my house. I guess because it has its own external antenna it makes it easier. It has text to speech, red light and speed camera alerts, AV IN channel, media player and it's very user friendly. The person at the store even told me it has TMS but I need to do something....When you make a mistake, the re-routing calculation is very fast, in about 5 seconds it gives you new directions. So this is a BIG PLUS. One thing I noticed is that with some road names, instead of the street name it will tell you its code, e.g: S90 instead of, Hamilton RD etc...This is my first GPS.
Now, I don't know if this is common but some of the directions are pretty weird. For example, it will take me through a few different streets to take me to point B when in reality all I have to do is turn right in about 500 meters. This one took me to the left, then right, then straight, right, left BUT it did take me to point B. I just don't understand why can't it just say turn right in 600 meters etc...Is this normal?
Here is a review and a pic:
http://www.gizmodo.com.au/2007/07/hitachi_...screen_gps.htmlYou can see the antenna on the left sticking out when it's pulled out. Also, it's very precise when it comes to measuring the meters. The counter goes to 0 literally when you are in front of a street that you need to turn into.
What else, when you need to make a U-turn in a round about, it will say: "Take the exit on the round about to <street name>" and <street name> is the name of the street that you are currently on to. So that's the only thing you need to get use to. When you need to turn left or right on the round about, it will tell you "Take the exit to <street name> on the round about in 300 meters" and there is an arrow showing you where you need to turn.
Of course it has hands-free via Blue-tooth. Looks like a solid device....The mounting is extremely easy. It has a suction thingie that you stick on the window and once you stick it, it has a handle that you need to push down (I think) to create a vacuum so that it stays on the window. There is a bracket that attaches to this that holds the device.
Please tell me what you think.
