I agree completely with some the posters on this site about the multi-functional mirror. I'm debating if I should spend the money on this device...and the conclusion is yes. Here are my reasons:dinu01 said:Since I'm tinting the windows I don't usually get blinded by cars driving behind me. Also, over 90+% of my driving is done in places I know (Niagara Falls to Montreal on the 401). I also carry a map with me at all times. Paying $300+ for this mirror seems pointless.
I wanna hear though why it's so great and why I should blow that much money on it from the die-hard fans.
1. AUTO-DIMMING: As stated by some, when SUVs or big trucks are behind you the mirror kicks in and adjusts accordingly. This also pertains to some vehicles with modified halogen bulbs that doesn't have a direct beam and shines everywhere, including Xenon HIDs, the mirror works wonders. Tint is another good option, but I've had tint many times before in the past and it serves a good purpose, but sometimes not. I have a problem with the drastic difference in darkness that tint creates when I don't want it to. For say, when my eyes are focusing on what's in front of me (no tint), and when I need to look to the rear or side windows (with tint) for other obstacles...it throws off my perception...almost like a blind spot. Also, tint with the higher grade metallic film for the Mazda 3 Hatchback is estimated at $220. I can get this mirror for $244 w/out install.
2. TEMPERATURE: This feature is more of a novelty...but cool in any case.
3. COMPASS: I'm pretty good at figuring out which direction I'm heading, but when I'm visiting cities like San Francisco with millions of street lights and turns...yada yada yada, it can become quite confusing to know which direction you are heading in.
4. HOMELINK: I've got this big clunker of a remote for my house and my mom's hanging on my visor. I hate it...too busy and creates a less functional visor when in use. Everytime I go to use the visor, one of those remotes fall or obstructs my view... :x . It's nice to have this feature integrated into the mirror without losing functionality with the visor.
I think its a nice addition to the car and there are features that for some...it does serve a good purpose. On a side note, I've never had any of these features before, and I was told by friends that I wouldn't miss it since I never had it...so save your money. But that's like saying: "You have a 486 66Mhz computer that works fine...don't fix it if its not broken"...wrong!
Just my .02 cents worth
