I was curious about all the different types of GPS devices there are out there. The availability seems to change so rapidly I was wondering if there was a database for all that is available and all that will be coming out soon.

I also get asked soooo many time per day from my customers about connectors on the back of their GPS devices, only im not sure which is which... There are MC, MCX, MMCX, (Reversed Polarity) MMCX, etc. any know where I could find out more about each GPS unit and/or schematics of them?

Really appreate any feedback.

Thanks
