Miata5201 Posted October 18, 2018 Report Share Posted October 18, 2018 (edited) I mistakenly installed the firmware for a AVIC-5200NEX on to my AVIC-5201NEX unit which wiped out my navigation as well as a few other features. I want to revert to previous firmware; the proper one for the 5201, but understand that Pioneer makes this very difficult. As I cant afford to send the unit in for "repair" (or the cost there of) and seeing as I am certain there is a way to achieve this with the proper information, I am hoping that someone on the forum might have the work-around? Please respond and let me know ASAP. Cheers all. Warmly, m UPDATE: So, after several weeks of having this request for information assistance posted to the site, I have noted that not one single person has made a reply... not even one to "wish me luck" solving this problem that I indeed placed myself in to... Of course I am disappointed. Is this the fact of it that no one of this forum has any idea at all how I might install the proper firmware on to me 5201? If that is the case, well, so be it... it was worth a try.... Thanks regardless of the lack of a positive outcome and I wish all on the forum well. Cheers Edited November 8, 2018 by Miata5201 Update Quote Link to post Share on other sites
krankintacoma Posted November 10, 2018 Report Share Posted November 10, 2018 Have you tried re-updating with the correct software update? Quote Link to post Share on other sites
Rocinante Posted November 10, 2018 Report Share Posted November 10, 2018 These units appear to be flexible with bad firmware installs. Try uploading the proper firmware to your unit. It worked for me after my navigation features were eliminated due to some kind of glitch. Quote Link to post Share on other sites
Miata5201 Posted November 22, 2018 Author Report Share Posted November 22, 2018 Thank you both for the suggestion. It is my belief that I did try to install the proper version with no success. However, it has been awhile as I abandoned the project while I had to do some work as well as to give myself a little rest from the frustration of attempting to resolve the problem. I've recovered a wee bit now and am going to refocus my attention to this next week. I ghad thought that if Pioneer releases a new update for my actual unit that it might overwrite the misapplied one. The last time I looked there was no further update but I am going to try again in the next few days. I will say a few prayers as it looks like I probably need devine intervention to get this sorted... Thank again for your responses. Much appreciated as I was feeling sort of lonely before you commented. Cheers, M Quote Link to post Share on other sites
midnight407 Posted December 3, 2019 Report Share Posted December 3, 2019 did you ever get a resolution for this? Quote Link to post Share on other sites
Miata5201 Posted December 18, 2019 Author Report Share Posted December 18, 2019 i have never found a solution and no one on the forum has offered any useful advice I am sad to report. I'm still hoping to figure it out one day as the unit has lost much of its functionality. Quote Link to post Share on other sites
