Hi capt. I'll admit it, I don't like being told my 172c is obsolete and therefore, like apple, I must bow to the gods of 'make money by forcing you to update' mind set that has spread like a virus in most progressive data tech companies. Seems like there bottom line is ' screw support, make them buy new.' So now here I sit with perfectly good old Garmin 172C maps chart/plot and a new area to fish (moved boat from montauk, ny to margate,nj ) with a massive tidal range (6') to deal with as well as a post hurricane complete rearrange of marked channels to avoid grounding which have still not been addressed, and no way of updating my bluechart data card.
I found one on eBay a month ago and it turned out to be from 2003, which is sooo off that the back water channels have me marked on land half the time. No bueno. So the fella at west marine ambled over seeing that i was looking at the Garmin display and informed me that he would be happy to sell me a new unit but there was nothing he could do for my 'obsolete' 7 year old 172c. Now, I may not be the brightest candle on the alter, but sure seems like there's a way to burn a data card with newer cartography on it, since all of there data is derived from NOAA and other gov. affiliated agency's. I went to the tablet i use, Samsung galaxy, and downloaded MX marine for $6.99 and then installed the FREE NOAA raster charts, works like a dream, waaay accurate, i kid you not, dam thing was rite on the money. But, the battery can not be charged while in use, and, of coarse, the MX app chews batt life like a drunk on chicken wings, not that there's anything wrong with wings after a few. Anywho, I'd like to think of myself as a bit of a sharpie in the rehelm of angling with a little McGyver mixed in ( emergency tape and shark wire my go to fix it) for work arounds, so this bit of technical 'no can do amigo' just dose not sit right with me, my dad was 27 year navy sub mechanic-diesel/nuke, he gave me the boat after he completely rebuilt the engine block up, I know your the Obi Wan of GPS tech, I've read your posts, is there any way i can burn a new data set on a blank card ( legally bought ) that would work in my 172c maps? Any help would be greatly appreciated.
