I'm new to this site and I find getting a worthwhile answer is difficult from some of the posters. If I ask for an opinion I expect something other than smart-ass criticism from a frequent flyer on your forums like djrams80. If I knew everything about radar I wouldn't have come to this site to begin with. Overall, I have learned that Cobra is not a good choice. For a motorcycle used 4 months a year in the central US, I don't want to spend a ton of money. I have learned that I can't get all the functions I want in any unit. Having the headphone output, compass, and decent KA reception would be my short list, but I can't even find that. An analog compass does not work well on a Honda Goldwing. I've have tried some motorcycle designed units. The bike speaker system and other electronics seems to pull the compass off.
Yes, I do have an older GPS on the bike but it's difficult to see in the daylight and change pages to see my direction quickly. So, if anyone of the critical posters would care to buy me a Garmin Zumo 550 GPS and a high-end Radar with headphone jack I will be happy and never ask a stupid irritating question again.
