Thanks!

But, the maps download seems to be the worst. Anyone have a mirror for that?

A huge shout out to 718socal for his support today!

Amazing community of folks here that really help each other out....

daaa nope

Any chance you can also offer a fast link for the P87 maps?

I've been using FDM with some success (it was what eventually downloaded the P85's) but the P87 is taking FOREVER. I'm on my 6th? 7th? attempt now - so far each time it downloads about 1.3GB worth and then just sits at 0 kb/s with only 1 connection.

I'll see what I can do.

daaa nope

I think? I am good! Finally downloaded successfully AND passed validation. (The only other time it completed the download, I got a bunch of data errors when trying to unpack the 7z.)

Westcoast

Are you just talking about 7z being able to unpack it, or something like MD5?

daaa nope

The first completed download failed to unpack via 7Z.

Thanks for all the help so far, especially reinforcing the suggestion to use the download manager. I have followed the video instructions to the point of accessing the GEM. The combination of car+tuner buttons does not seem to work for me. Am I missing something?

Thanks again.

718socal

It takes practice. Press CAR then TUNER a second later. Make sure the SD card is inserted in SD1slot.

It took a few more tries but I got it. Upgrade finished, AA and Nav online. My maps are 2019/2020, so I'll consider trying that with the maps which finally downloaded.

Thanks again!!!!!

Westcoast

Maps will be just using the appropriate PCM menu's, No AIO or MIB required. Just download the NAV files, and place in the root of the SDcard, insert into SD1, recommend doing P85 first followed by P87.

daaa nope

Just note - the P85 took 45-50 minutes to complete. P87 took 35 minutes to complete.

SANITY CHECK PLEASE:

First, a big thanks to all here who have contributed. I'm about ready to do the AIO patch on my 2021 GT4, and just want to double-check and ask a few questions.

My goal is to enable CarPlay and Android Auto. My car has Nav and the current PCM version is: MHI2_US_POG_P5177 (1453). I've downloaded "MHI2_US_POG11_K5186_1_MU1476_AIO_20220703" and prepared an SD card with it. I also have a battery tender to use during the update process.

Questions:Thanks,
Ed

Westcoast

Yes, that it the correct and latest version of AIO to do what you want to do. IIRC it takes about 20-30 minutes, be patient and follow the onscreen instructions, do not touch controls or press buttons until asked to do so, and above all when the screen goes blank, wait, and then before you touch anything wait again!

See post # 2 for the button combinations for and the different screens, but again, hands off until directed to do something!

Okay, I must be missing something here. I've tried different delays between hitting the CAR and the TUNER buttons and holding them different lengths of time. I have not been able to get into GEM.
