A long story trying to keep short but is long! I got started with a Junson AHU Radio MediaTek based 8227L DEMO 2GB RAM/32GB Storage that I had bought as a bundled kit with my cars dash kit and wiring harness for a 2015 Ford Fusion SE based radio.

This is where I had a bit of a learning curve. The radio kit required I use my cars HVAC motherboard and install it within the new radios dash face, there are two metal brackets that are used: a lower one to mount the display to the bracket and a top one that the heatsink and radio motherboard mount to with the ribbon cables attaching to the top mount radio parts. Only problem was the cables were all too short to reach! I cut down the mount and used 3M double side tape to mount the internal bracket to the back of the face kit. I live in a hot climate and thought this would not work long before things would potentially come apart. I eventually got the needed cables for this and repaired the mounts, bought a 2nd HVAC Ford board from Ebay and put it up for sale after I bought a new dash installation kit and wiring harness from Aliexpress and started shopping for a better spec'd radio.

I shopped Ebay again and bought a HIZPO/Ossurett branded AHU based on Topways TS-18 mother board with 3GB RAM/32GB Storage. The radios hardware works great but I did not like the build in software for media playback namely for music. It would only random play on a single album and not the entire USB source drive. I then bought the one below before trying to find a better APP on Google Play Store.

Ebay seller Hizpo/Ossurett bramds one is a ALPS built model FF-8677Q CPU that was (suppossed to be) a 4GB DDR4 RAM/32GB Storage which I had Bluetooth connectivity issues with a Motorola Power G series phone (connected to radio I could hear in coming callers but they could not hear me no matter what settings I read and tried to use. The seller exchanged the radio for another but that did not solve the issue either) I then bought a new Nokia cell phone N400 5G that works perfectly with the radios bluetooth. At some point I installed Junson software that works well, has a more updated look, has been widely supported here on XDA forums. The Junson software revealed the radios true RAM to actually be 2GB and so has other test APP's. The seller would not admit to selling me a falsely misrepresented model and that's were I'm at today. The radio works well for me now and I don't plan on swapping it out anymore. It supports upto a 2TB drive, the units Android Auto works correctly, the phone works in all respects. I installed a 4-channel amp from Planet Audio thats using the radio's RCA line outputs that works for signals. A powered sub from MTX , with SKAR front component 2-ways, and 2-way coax in the rear doors. A lot of time and effort over the last couple of years to get something that is making me happy and proud of.

I kept the AHU 8557 based radio for a couple of days until I got the software to make it work from the seller, then tested some more but came to the conclusion I was not overwelmed with this radio enough to attempt headunit removal and install again. It well may have had the ability to work fine but as you now know I have two radios that meet my needs well enough.

I hope this radio works out well for you! I did like the DSP having presets for SRS, Dolby, and DTS sound curves.
