I've read great reviews for Avant 4 and it looks more factory.

My understanding is that 10.25 unit is similar but no buttons, bigger screen and it doesn't look OEM.

Mine has NAV but no DSP, only Hifi option so I'm thinking to go with these options:

Please choose CPU platform
PX6 | 4GB RAM | 64GB ROM | 6-core CPU | Android 10
Add optional IBUS USB module (includes paid IBUS app license)?
No - I do not have DSP
What side is your steering wheel on?
Left-hand drive (AVN4416-LHD)
Do you have the OEM factory DSP amplifier?
No
Do you have / had the factory navigation?
YES - add required Quadlock 6M Navigation Extension Cable (SKU: QDBAV6MC)
Add optional Advanced DSP Sound Processor Chipset with 15 EQ Band
No - I understand the DSP chipset can Not be added later.
Add optional AutoPlay Dongle w/ Support for CarPlay and A-Auto
No
Optional Accessories
None
iGO GPS Maps MicroSD Card (No internet required)
None
Add optional Tire Pressure Monitoring System (Model: TPMS-USB)
No
Add optional Digital TV Tuner
No

My understanding is also that I can buy ibus app much cheaper from original source:
