Evo 4g LTE Car Stereo Idea
Ok, so I have an old evo 4g lte lying around and I have a few ideas for it. One of them is to turn it into a car stereo.
I want to basically make it power on when the car turns on by removing the battery and connecting it directly to vehicle power via USB - and stick it to the dashboard of the car to use as a music player. I would like to be able to use google play music (in conjunction with the wifi hotspot on my new Nexus 4 or possibly just with the onboard music on the 32gb microSD card.)
A few issues I see as potentially problematic - the OS boot times. the headphone jack puts out weak signal so I plan to use a bluetooth connection to the radio. I may want to use the phone in the house. It may get stolen.
Anyway, has anybody done anything like this before? I have an old HP Touchpad that I might like to use for a head unit at some point as well. Android is pretty cool.
It might be feasible using a battery but the issue I've seen with that is that the charge it occasionally gets from the car when it's powered on is not enough to keep the phone always going, hence it will eventually go dead and require removal for charging - limiting mounting options to something where it's easy to remove - which is not a good thing for the Touchpad, as it is too big to just stick somewhere.
I hope this was an OK place to drop this. LMK what you think.
