[MTCB Android Head Units Q&A] typos1:
JY standards for "Joyous" as in Shenzhen Joyous the manufacturer of the JY units, "Joying" is a re-seller of JY units, so named to suggest theyre the manufacturers themselves.

Yes, you can - its probably made by one of the smaller companies like JY, KYD etc - its using the standard "MTC" launcher

You probably need a power injector so your OEM booster will work.

I have the same problem with my GPS slot on whatever firmware I use.

Just FYI, you have a KGL unit, not an Erisin, Erisin are simply a re-seller.

This is a known issue on these units, its been discussed before and is down to the implementation of AF on the radio IC, its particularly a problem for Italian users as there are so many stations in Italy, apparently there are 3 ways to work the AF function and the way the developers have done it means it does not work the way most would expect, the only way round it would be to modify the radio apk, for more info use the thread search function. Its nothing to do with the incorrect labelling of PTY info, which is a separate issue.

My Klyde came with a cooling fan like most earlier ones, on later ones KLD removed the fan but left the hole, the very latest units dont even have the hole for the fan - its filled as you say.

Its a "BN" unit and is indeed one of the types in this thread, so far I think only [MENTION=1211910]OneCheekyDevil[/MENTION] has one.

The screenshots are wrong - its a "BN" version.

I agree about touchscreens in cars - hard buttons are easier and quicker to use, just as they are for text input generally and especially for one handed text input on mobile devices, touchscrens are great, but NOT for everything.

No, its a Joyous sold by Joying, Joying are a just a re-seller.

Interesting - in the past people have asked to ENABLE the lockscreen on these devices, but no one managed to do it, I think [MENTION=6005745]ptclabs[/MENTION] spent a while trying to though.

No, its "BN" as I said above. I m afraid that NONE of these units support video from SD card to rear screens.

Eonon are just a re-seller, to find out what unit you have go to the about screen, its probably a KLD or a JY. KLD are working on a DAB box but there has to be modifications to the main board for it to work so it wont be retro-fittable. Certain types of DVB-T dongle using a specific type of Realtek chipset, can also pick up DAB a few people have done it in the past, if you search the thread for "Wavesink" you should find the posts. If your car has an OEM antenna booster a power injector may help with FM reception.

Its a "BN" unit, see above.

I m afraid this is standard procedure with buying from China but it usually does specify "buyer pays return postage" on the listings.

You could try the Toshiba TB2929, its a direct replacement and should give an improvement in sound quality.

What car and unit do you have ? My guess is that you have a KGL and a VW group car, am I right ? I say this because similar problems with KGLs and VW group cars with amplified rear speakers have been reported before.

Interesting, great agentdr8, this opens up a few more possibilities on these units.

Its already on the server, its been rooted and has a few minor mods, such as 3Gb of space for apps and DSA's script to enable installation of TomTom maps, but its pretty uch the standard ROM apart from this, if youre so against root (why?) there are a couple of versions on the fileserver that arent rooted but theyre not labelled, you could try emailing KGL and asking for it or searching the thread for a post from the last few months with links to the latest KGL one..

I know you and [MENTION=3590033]Malaysk[/MENTION] have worked together to sort this "issue" but I think a better solution would be for Malaysk to swap around the functionality of the power button - instead of a short press for screen off (which means a reboot to get the screen back on again on full touch models) and a long press for the power off menu, it should be a short press for power off menu and a long press for screen off, this would prevent full touch users having to reboot (and having to turn off their car) but still enable them to use the power off menu and would mean less messing about with 2 versions a one with the buttun and one without.

Although I guess this could be harder than I think to do as the standard Android power off menu works with short press for screen off/long for power off menu and it would have to be re-written.

EDIT: Just seen this:

all the options youve added kinda sorts it then !

FYI you do not have an Erisin unit, they are just a re-seller, to find out what unit you have go to your 'about" screen.

For CAN Bus, go into factory settings and try all the VW settings and see which works best, if none displays all the info you want then theres not a lot you can do about it apart from modifying the app.

The unit in the link you posted is totally different to these, its an AN21-U. Klyde are about to start selling TPMS devices, I dont know yet whether they require modifications to the board or are designed specifically for these units or not. I m waiting for more info and I ll get one to try it, when I know more I ll post the info.

Your problem is that youve flashed an incompatible ROM for you unit - youve flashed an 8Gb ROM on a 16Gb device - I m surprised it even flashed successfully.

As yours is the first 16Gb unit in this thread neither DSA or Malaysk have written 16Gb ROMs

You could ask DSA nicely to do a 16Gb version of one of his ROMs and ask Malaysk as well, no doubt more people will be asking as more 16Gb versions are sold . . .
