UL135N2 Vs. UM135N2 info
#1
Have a UL135N2 and looking to buy another one for a different car.  Anyone know what's the difference between UL135N2 and the UM135N2 ?

It is simply the next model: alphabetically M comes after L.
Same for the JY-VL130N2 and JY-VM130N2, or UL128N2 and UM128N2, and all the other models from Joying.

There are only minor detail differences on the mainboard I think.

My unit is broken and I had to send photos of specific locations of chipsets, condensators etc., but they didn't care at all about the central 5009 block.
Have a look at my Joying_Extra_Tools.apk and the rooting script

Information 
I believe that one difference is that there is no video out RCA jack on the UM model that is present on the UL model.

The two units have a different System on Module. FYT5009 on the "L" and FYT6021 on the "M". The 6021 is a much better module for the simple reason that it is connected to the mainboard with a SOCKET. 5009's are soldered on, and because of the extreme temperature swings, they stress out the solder joints, which eventually fail.

You should have asked if we recommend you buy ANY of them.
In which case, I would have answered with a definite NO WAY.

I sure as hell won't be giving these dipshits any more money.

Then I have a "Frankenstein" unit...  mine is described as a CA-JY-UL124N2 (bought here), but it is definitely a 6021 inside... the module is on sockets and has the "heat sink" top...

Another inconsistency...

That's not an inconsistency. Its an error.
You have a UM. End of story.

Sorry you have a bad experience.  My 1st unit works great and I hope my 2nd one will work great too.  For a couple of hundred dollar, I am willing to take those risks / odds

Just try asking them for the kernel source code (which they are LEGALLY obligated to provide).
