:newsmile100: My daughter had problems with her laptop freezing up on her last year. First thing I asked her was what is she resting it on while working.. Had it on her lap or on the bed. Simple solution was to put it on a cutting board and she's had no problem since. I'd think repeated long term use without proper ventilation will kill them sooner. Short term will affect there longevity but not as much.
I know a car GPS might not be the ideal because I most likely will not be able to hear any directions but as long as I use it as a backup to proper maps it should do.
For the cost though, I could buy a few car GPS's for the price of one Zumo and for as often as I use them it'll be easier on the wallet.
Mind you, I've found out the hard way that GPS's are not 100% accurate. Had mine try to send us down a dirt road in North Dakota last year. . . . . . . . I'll be spending the money on the updates this year though. . . . . .
I cant' say for other Iphone Navigation Apps but the Navigon App by Garmin supposedly uses true GPS Satellite signals so losing cell phone coverage should not be a factor for navigating while using the Navigon App.
I purchased a garmin 550 a few years ago and just now installing on my 2003 Harley ultra. please tell me how to run it threw the radio speakers and do I need an ext antenna for the xm radio in it or is it built inI've been using the Zumo 660 (and the Zumo 550 before that) for the last few years and many thousands of miles. It gives me the freedom to explore any road knowing I'm never lost. I first had it installed on my Fatboy, then transferred it to my Road King after selling that bike. It also works great in the car. Comes with everything you could possibly need for mounting. The 550 came with a AC charger that I never used. My friend has the Harley version, works the same, just no flexibility on mounting options. Some of the best money I've ever spent on the motorcycle.
