Just to let you older GO users know, Circuit City is selling the TomTom GO Permanent Mount kit for only . This is seems to be still listed in most online stores for 9, so that's an excellent savings. The direct link is [URL="http://www.circuitcity.com/ssm/TomTom-Permanent-Docking-Kit-9D00012/sem/rpsm/oid/138328/rpem/ccd/productDetail.do"]HERE[/URL].\r\n\r\nI can't figure out if I want this or not. To be completely honest, I haven't been able to figure out what the end product will look like installed. Do you still use the suction cup mount or does this come with some other method of mounting? I realize it auto dims your TomTom at night, plays the voice instructions over the speakers, adds an external antenna, and auto on/off with the ignition. However, my current installation already does the on/off thing (I installed an under-the-dash hidden 12v plug so my power cable is rather hidden), and I've seen bad reviews about this permanent mount system causes humming noises over the stereo system. \r\n\r\nDoes anyone have this accessory and what's your opinion on it?\r\n\r\nThanks.
