Intellimap 642 IGPS

[bronzeback45]

I just bought a 642 igps and the new FHP east chip went to chickamauga and my unit will not show detailed mapping . Lowrance said my unit needs to be updated so they are sending me a chip to install and update it .
Does this sound correct to you guys ? Also , when I set my time and overlay data my unit wont save info. Is it because I'm unplugging the unit ? I have to remove my unit from boat because its stored outside.

Thanks , bronzeback45emoScratch

Sometimes I have to re-insert the chip to get the unit to read the correct map. Be sure you go into the "Map Data" on the first "menu" screen and select the "Tennessee" option. I was able to download the unit upgrade to a blank SD card from the Eagle website and transfer to my unit without any problems. </p>
