As an associate at a “big box store” (in Eden Prairie, MN, off of 494), let me weigh in here.
If you have a map chip/unit issue, bring them both in. I’ll hook your unit up to one of our display models’ power cords, and fire it up. If the chip isn’t reading/acting wonky, I’ll throw it in a display model and see what happens. That’s how we determine if it’s a chip issue, or a unit issue.
The gentleman from Skeeter (sorry, forgot your username) who mentioned updates is 110% correct. It takes a blank SD card (which I almost promise that you have access to, almost everyone has one) that costs $5 on Amazon, or $10-20 at Best Buy/Target/Wal-Mart. Go to Lowrance/HB’s site, go to support, and updates. Then find the latest one and download it. Save it to the card, put it in your unit, and turn it on. Bing bang boom, most of the time the problem is solved. Worst case, you can do a soft/hard reset. Yes you may lose your data (unless you use that handy blank card again to save your way points, routes, and tracks to), but it’ll reset the unit to factory defaults, and that should solve most problems. If neither of those solutions work, you have a serious software issue, or a hardware issue, and it’s time to service the unit.
Oh, and if you’re really technologically illiterate, call our store. A few of us took money/time out of our own pocket and bought cards to download the latest updates to. Bring in your unit and we’ll update it for you.
Having said that, I’ve turned away more than a few people because their units were past 30 days old. Well to make that clear, my manager turned them away while I looked at them sympathetically, since those policies are way above my pay grade.
As a bit of a techy I have to say, having Apple be a main competitor in this race would be terrible! I’d love for one of the other tech giants to get involved, but anyone who thinks Apple products are easy to troubleshoot/fix, or are actually worth their MSRP is sadly ill-informed. No offense, but had to be said. lol
