Yeah, I would go with upgrading the entire HU at that pointI would try and find a ham radio dealer/repair place. Or find whom ever sells and services radios for the local police/fire/ambulance services. They might be able to re-crystal the radio for your country. I don't know if it is possible though.
Still probably wouldn't work. The band pass filters inside the radio are tuned for the odd off-centre frequencies. His best bet is just purchase a new radio...Are you using the scan feature? Scan only picks up active freqs. You should be able to manually roll thru those freqs. Maybe I am wrong.
id you go to al salam street you will fimd one for the fj for 2000 dirhams that has everything you can imagine including the reverse camera my brother is getting it with him now hes on his way to the statesYes Iam from Abudhabi ,I was thinking of Kenwood, but the Dvd bluetooth Navigation version of unknown brands are very tempting cost wise especially if a waranty is given.
