There are various points not understood easily though the content of this document is a very interesting content. I think that you should improve it to a comprehensible content because it is difficult though it is a good content overall.

7. What specific suggestions for improving the articles can you make? I show various methods of improving this article. This procedure is plainly changed though this article shows the use procedure of the car navigation system. The content is very difficult though this article writes details of the mechanism of the car navigation system, so it rewrites it as even the person who doesn't know the car navigation system understands the content of this article. It is directed that this explanation is concisely written though this article explains the relation between the car navigation system and the car.

8. Identify three basic differences between how your group would author a similar document and how this author authored it (as you see it in the link). I explain three differences with the author of this article. Our group writes very comprehensible and concisely though this article writes the explanation of the car navigation system the first very difficultly. After in addition to this procedure, our group explains in detail though the author of this article is secondarily writing the procedure of the car navigation system. Our group writes though the author of this article is grammatically sentences of difficult writing thirdly by the writing that the child also understands.

9. Study the following video carefully and then summarize 10 major points that you were able to understand. I saw this animation and variety was able to be understood. It came to understand whereabouts only with the cellular phone the GPS function had adhered to a recent cellular phone. Whereabouts can be confirmed with GPS of the cellular phone in the map. It came to be able to transmit to not only the whereabouts confirmation but also the police recently. GPS is applied to iPhone. GPS is applied variously and is very convenient. The usage will develop to GPS more in the age of various in the future. It is easy to think about the application of GPS very much. GPS is a function very necessary for the cellular phone. To put it on the cellular phone, the goodness of GPS is drawn out. It is easy to use it because the purpose of GPS is clear.

10. Study the following video carefully and then summarize 10 major points that you were able to understand. I saw this animation and variety was able to be understood. As for this animation, the convenience of GPS used with iPhone has been understood. When studying the map, GPS of iPhone does a very good role. iPhone uses latest GPS and is very convenient. As for the map of iPhone, the function of the expansion and the reduction is excellent. iPhone has a special application unlike the cellular phone. GPS is very suitable for the confirmation of the position. GPS clearly teaches the place in the destination. The development of GPS is very useful for iPhone. iPhone has a useful function in the age from now. The number of those who have iPhone will increase in the future. GPS of iPhone is used by various usages.
