My C100 arrived this morning. I immediately unpacked it and did an update. But, as advertised, it already had the latest updates installed. But I updated anyway just to get familiar with the process. Update process worked great. The software found a free Com Port and the update took about 3 minutes.
Next I took it out to my truck to see how quickly it locked on the satellites. First thing I noticed was a very long connection cable. I suspect it's the same one as the Cheetah mirror, so it's made to go from the mirror all the way around the window to the lighter plug. But for a dash or steering column mount, this cord is way too long. Perhaps Cheetah will sell a shorter coiled cord in the future? One like the radar detectors use would be ideal for the C100.
Second thing I noticed was the connector to the C100 unit didn't go in all the way. I had read about this with the Cheetah mirror, so it wasn't a big surprise. The unit functioned fine, it just looked wrong.
Lockon to the satellites was quick. But the volume as shipped was loud!!! I found the volume knob and turned it down. Much more understandable voice when lowered. I set the clock, and unlike the other product made by the competition, this clock was accurate even after it was turned off and retains the Mountain Standard Time setting I use. Glad to see that
Brightness/visibility was fine for me. I see no need or reason to dim it down.
I drove away and at 9 MPH the clock switched to speedometer mode. I knew my cruise control only worked at exactly 25 MPH so I brought the speed up to 24MPH and hit the cruise button. Nothing. Excellent!!! I nudged the speed reading up to 25MPH and held it there and hit the cruise button and the cruise activated. So I know that the accuracy of the GPS is quite good at low speed. On the way out of town I passed two squads, one using radar and one just passing by. (I don't have the link to use a detector yet, but I am beginning to think I will get one.) The C100 got me up to 55MPH and I set the cruise control. I passed the radar squad and no lights came on, so I can assume I was okay with the reading.
Mounting...the unit comes with a mounting bracket and suction cups. But it also warns in the instructions against mounting it in the sun. So I don't see much point in the mounting bracket. A better solution would be to include a couple of velcro strips. Since the C100 has excellent reception of the GPS signal, it can be placed just about anywhere. Since I am mainly using it for a speedometer, I velcroed it to the top of my steering column. I have perfect vision of it and no worries about it being exposed to the sun. As an added protection/security measure, I found some black cloth and covered it up when I park. So it's all but invisible from any prying eyes.
One complaint I have is the lack of protection of the display window in the box. Mine came with a few abrasions on it. It doesn't affect the readout, but it is a shame that they didn't take the extra effort to protect it. It wouldn't be all that expensive to cover the display window with a peel-off piece of plastic like they put on new cellphone displays. The little ziplock bag it was enclosed in was unzipped when I got it, so that's not a good way to protect it.
Compass display...really neat. It uses the standard N,S,W,E in little letters that are visible even in bright sunshine. For NW they use a little arrow pointing between N and W. Still pretty cool.
The on/off switch...I really like that it has this feature. My cigarette lighter plug doesn't shut off with the engine. So this switch is a nice feature. However, I wonder at the durability of the switch. Too many times switching it off and on may wear it out quickly. It's a very small switch and I just don't know about it's durability.
So to sum up the things I think need improvement:
#1 A shorter coiled power cord. One the size of most radar detectors would be fine.
#2 Connector needs to go in further.
#3 Toss the mounting bracket and suction cups and include velcro instead.
#4 Better protection of the display lens during shipment. Suggest removeable plastic cover of the lens.
Overall I am very happy with this unit. It seems well made and works great. All it needs is some minor improvements/changes and it will be perfect. It's already far superior to the competition.
