Just get a aftermarket…
Just get a aftermarket remote starter should run about $300 and u never have to pay for it again. U can get it to work off factory remote or get separate remotes for longer distance. Yea u shouldn’t have to go through all that but it’s either that or pay another monthly fee on top of vehicle payment. And as for navigation all newer vehicles should have Apple car play and android auto which once connected u can use ur navigation on ur phone and it mirrors on to the radio.
