halo guys!!! It takes 1.5 full days for me to read all these 50 pages of this topic..
I'm a newbie in gps and is planning to buy a gps called 'GPS BAY 3303' with RM399 as citibank is having a promotion. (http://www.gpsbay.com/index.php?mid=603&p=products-item&id=728).
Anyone tried this gps can share their experience?

I have few questions need to ask all the expert hope you are able to help:

1. My lovely myvi is tinted but not V-Cool. So is there any differences in terms of the satellite signal reception between out side a car and inside the car (edge of the windshield)? Just want to know will the windshield block some signal....

2. Can an external antena boost the satellite reception or it just an extension which the power of reception is same with the build in antena?

3. Is there any reception differences if I place my gps unit to the edge of windshield (without using external antena), and if I place the external antena to the edge of the windshield and connect it to my gps unit inside my car? I ask because I don't 1 to put my gsp unit to the edge of the windshield as it will 'hurt' under direct sunlight (even just few minutes drive) and by putting the external antena outside the car might attract ppl to steal it or break the antena. What do you think?

4. Will the vibration from car hurt the gps unit ah? 

5. I remember JPJ doesn't allow ppl to put LCD screen in front of front passenger/driver, will the police block us if he saw the gps unit and take advantage to saman us? i think in malaysia it possible?... 

6. Saw many ppl talk about the mapking and malsingmap maps. Can we have a conclusion which 1 is the best? in term of? why?

Thank you guys in advance..... heehee... this forum rock!! it's a 'gps' for questions and answer... heehee...
