I just bought a GPS-Bay E668, and having very poor signal. The support centre suggests that it's due to my V-kool tinting.
1) Any good suggestion how I can overcome this problem? I read through some forum and some commented that their GPS system can still work with V-kool?
2) Some suggested to cut a small hole at the V-kool tinting, any suggestion which will be the best location to do so? I will not be mounting the GPS in the car, will only bring it out as and when I need to use the device.
3) Another option is to buy the external antenna, anyone knows how much does the external antenna for GPS-Bay E668 cost? How is it being fixed? Just plug into the additional port on the GPS device? If so, isn't it still "within" the car and the satellite signal blocked by V-kool?

Appreciate any experience sharing, suggestions and how best I can overcome my problem without spending too much.....
