Below is one review from JC
“Nice product. good quality and good price. I installed this in my 2013 Jeep Wrangler to replace factory RHB 430N. The Pumpkin unit performs very well and true Android 4.4. is awesome. I have installed many apps from Google Play and had no problems. I would give it 5 stars, but here are my reservations (in order of importance) 1. **IMPORTANT** Security setting (screen lock/pin code/etc.) have been removed or disabled. So anyone who has access to the unit (if it’s stolen) will have my contacts, email, music, etc. There should be an option for screen lock/unlock at power up to prevent this. 2. Documentation is a little weak and no specs for steering wheel control emulation makes getting that work a hassle – trial and error. 3. The radio tuner is a little weak. Local stations that I have no trouble receiving on other radios come and and out. 4. The ‘stock’ launcher is a little limited so I am using Nova Launcher. This works great, but there is no way to turn radio app ‘off’ so once you launch it, it will keep playing in the background unless you kill it. 5. The unit takes a few moments to ‘boot’ so having a sleep mode would be ideal and could not be much of a drain on battery. 6. The stock music app is pretty much useless – no way to search for songs/artists, just scrolling. If you have more than a couple dozen songs stored on SD card, you have to download another player that will let you search. I am using Google Play Music and it’s working great. With just a little more polish on the software side and I’d give it 5 stars. Note: I am using a 64GB micro SD card and it’s working great. Windows users will have to download an SD formatter, but formatting as FAT32 on 64GB allows this unit to see all 64GB. Holds a LOT of my music. ”
