First off, what are they going to retail for? Me, I was using a Garmin iqueue 3600 for my on-jeep navigation. Until last week, when the backlight died. I needed another one, and looked around.
Garmin actually makes one specifically for jeeps. It can only be orderd through a dealer, and must be installed. Looking at it, its simply a Garmin Quest II in a nifty little case thats installed onto the dash of a wrangler. Well, I started thinking...this is what I am looking for, but dont necessarily need it hardwired into my jeep.
It is waterproof, capable of both road and offroad navigation, has removeable memory, and is capable of loading custom POIs. The downside was the price. Garmin listed the Quest II for 700ish. I went to megaGPS.com, and found the same model for under $500. Again, expensive, but I use mine quite extensively, & am getting a good amount of cach back from taxes. Here is the unit:
Quest II
Again, shop around for better prices. I've used Garmin exclusively, & never had a problem. But, its like coke & pepsi: people are loyal to their brands.
