Yeah, as I've said many times on here, the HU is a POS for all kinds of reasons, probably the least of which being map updates (the underlying routing algorithms will still be poor, after all).
Getting it replaced and then integrating a rear vision camera and the right other audio bits for decent audio quality is still my highest mod priority. The idea of spending $2,500 for this kind of
thing when tablets run in the low hundreds does not, in the least, delight me or seem the right direction to head.
