Query: Got trees? Don't buy this.

Last year I purchased the Sportster with boombox and car docking station. Installation difficulties have made it at best disappointing and at worst, useless.Because of all the huge trees in Atlanta, positioning the boombox antenna is tricky. Once I did get it positioned on the deck, I found that reception was fine as long as I sat perfectly still. My slightest movement in any direction would cause the sound to cut out.The car kit is billed as "plug and play." That may be accurate if you are an electronics engineer and don't have a convertible. Running the cable for the antenna from outside the rear window to the receiver on the dash is not exactly a snap. For most people, finding a place to position the receiver cradle is a problem too because it requires quite a bit of space and can interfere with such things as airbags and visibility.Good luck--for those who can figure it out, satellite is worth it!
