As a new member, I can't post yet. From reading the forum, it appears a somewhat common problem is a broken mSD card. This happened to me on my NX702 when I repaired the screen drive (I'm not sure how it happened).
It appears there are enough files available to make a working card and some have done so. Since I don't know how to do this (and I'm sure there are a few others in this boat), would it be possible to post a walkthrough/sticky for those that no longer have their original card?
It's your forum, I'm not trying to upset you. I did read that post. I did download that file as well as all four of the 702 files (or so I thought), and put the 502 extracted contents into a folder called RTNavi. I was not sure where the 702 files went- two of them were 314K executables:
Clarion NX702E orig Primo 9.6.5_270089 w_o maps.7z.001.exe and Clarion NX702E orig Primo 9.6.5_270089 w_o maps.7z.003.exe
I clicked on these and the result was a popup that wanted to install something called Web Save, which I declined after finding out it was a coupon/ad plugin. The result for each was a 1KB file. It appears I only got one 500MB file, the one ending in 001, and it actually ends in part, so it appears to be an incomplete download. I will try & download until I have all four w/o the .part extension.
I found some iGO8 R3 map files and downloaded them. After reading the NX502 post, I had a question: Do they go in the same directory or another? I have no original card from which to look up or copy a file structure. Your latest answer clarifies this, thank you.
On occasion, I write how-to papers for automotive modifications. There are many things I know how to do thanks to decades of working on cars. But if I assume the reader also knows this- or even use an acronym such as SWC without explaining it means Steering Wheel Controls- then often the reader is left with questions or is at a point where they cannot perform the same task.
Thank you again for the added info. I will work on this, and try to write a step-by-step guide for beginners like me to use as I make progress.
I have performed additional research, downloaded all files, and ended up with an operational mSD card. I've written a 3 page how-to for this procedure with current links and saved it as a PDF. It is attached. If any errors or omissions are found, please reply here and I'll address them.
